Refractory Material/ Zircon Sand and Zircon Flour/ Powder
1.Structure of Zircon Sand and Zircon Powder
Zircon Sand, also known as Zircon, is a Chemical Compound, a Silicate of Zirconium, andits corresponding Chemical Formula is ZrSiO4. It occurs in nature as the Zircon, a Silicate Mineral. Ore is mined from natural deposits and concentrated by various techniques. It is separated from sand by Electrostatic and Electromagnetic methods. It can be made by fusion of SiO2 and ZrO2 in an arc furnace. It is usually colorless, but impurities induce various colorations. It is a fine white mineral powder that is chemically inert and stable.It is insoluble in water, acids, alkali and aqua regia. The tiny, round, solid ball shape of Zircon Sand provides a greater surface area for improved performance and dispersion in its application. It is also sometimes known as Zircon Flour, Zircon Powder, or Zirconium Silicon Oxide. Zircon is the generic name for Zirconium Silicate; the trade names are different (for example, Zircopax, Zircosil). It is used as an ingredient for its functional properties in several Industries.
2.Main Features of Zircon Sand and Zircon Powder

- Q:Refractory materials are needed for casting metallurgy.
- Refractory material used in foundry work is that refractories for cupola furnace? Cupola is a high temperature furnace which is used for melting molten iron, and refractory material adopted is mainly low iron high grade clay brick and clay lightweight insulation bricks, etc.foundry ingot refractory material is pearl sand (also known as pearl jewelry sand, fused ceramic, ceramic sand) it is made of high quality bauxite material by arc melting furnace.
- Q:Does refractory belong to metallurgical auxiliary materials?
- Refractory is widely used in industrial circle, such as metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate and power, and its coonsumption is the maximum in metallurgy, accounting for 50% to 60% in total output. In order to improve slag-corrosion resistance of furnace lining, usually choose carbon-containing refractory. Refractory of various furnace lining are respectively: For the body, it is clay brick; as for the lower part, bosh and middle, it is SiC brick; for furnace bottom, it is carbon brick. Lattice brick is an important refractory product used in air heating furnace and regenerative chamber. Refractory is widely used in metallurgy. In order to improve slag-corrosion resistance of lining. Central line in tuyere and hearth are high-alumina brick. Refractory consumption is the maximum in metallurgy, accounting for 50% to 60% in total output. For the bosh and middle, it is SiC brick. In order to improve its thermal storage capacity: The furnace stack is clay brick. It is defined as refractory where the physical and chemical properties allows its use in high temperature environments; The lower furnace body
- Q:Procedures for producing common refractory materials?
- The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.
- Q:Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports
- Fire resistance, combustion performance, combustion heat value, fire resistance, high temperature resistance, fire rating test and so on. Regular testing institutions are generally reported, Qingdao standard also can, the results are more accurate.
- Q:Does anyone know what kind of light fireproof materials are there?
- 二, 1, Gypsum plaster board With the building plaster as main raw material, gypsum plaster board is a kind of processed plate made by a special board for protective with an addition of additives and fibers as board core. Gypsum plaster board is characterized by light weight, sound insulation, heat insulation, strong processing performance and simple construction method. 2, Gypsum block Gypsum block is a kind of lightweight building gypsum product which is mainly made of building gypsum, and by adding water, stirring, casting and drying. During the process, , the fiber reinforced materials or light aggregates are allowed in, and the foaming agent can also be added. It has many advantages, such as sound insulation and fire prevention, convenient construction and so on. It is a kind of new and healthy wall material which produces low carbon, enhances environmental protection, and caters to the the times. 3, Fly ash brick is a new type of wall material, and bulk density is one of the main technical indexes. The weight of bulk density can be controlled according to the need of construction and adjustment of technical formula. The dry bulk density of the fly ash brick is about 1540 to 1640 kg / m 3, slightly lighter than the clay brick (1601800 kg /m 3). The flexural and compressive strength of fly ash brick is mainly determined by the production process, the formula and the hydrothermal synthesis reaction mode as well as the need of construction. According to the standards of architectural material industry (JC239 - 2001) released by People's Republic of China, the average value of the flexural strength is 2.5 ~ 6.2Mpa, compressive strength is between 10 ~ 30Mpa. I hope this will be helpful to you
- Q:What is the material composition of the new fire-resistant coating?
- New fire?retardant?coating materials are produced by non-toxic expanding materials and special process, with no pollution. Use natural bite when installing, without using the formaldehyde and other toxic glue. It consists of a variety of organic matters, so it adapts to the natural environment, with long time of fire-resistant; The fire-resistant time for new fire retardant module is up to 4 hours or more, three hours more than the standard prescribed by the state. It is composed by the specially formulated materials, with no flying smoke, good heat insulation effect, fast heat dissipation, scientific and rational design, easy using and no falling off and long period of effective.
- Q:What problems should be paid attention to while using refractory materials under a controlled atmosphere?
- Pay attention to the performance of the materials, and the use of non oxide materials!
- Q:What are the materials of insulation firebricks?
- The furnaces of firebricks are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.
- Q:What is the criterion of entry of refractory clay industry?
- There are two requirements: (a) Enterprises mining and processing high-alumina clay meet the national industrial policy, and in line with the requirements of mineral resources planning and industrial planning, industrial development planning of high alumina clay in provinces (autonomous regions and municipalities), urban planning, the whole land use planning, mineral resources planning, environmental protection and pollution prevention planning. (b) The building of new mines of high alumina clay in areas where exploitation of mines are restricted in national and local level should be strictly limited. It is prohibited to build new mines in areas where exploitation of mines is banned, and the mines have been built should be disposed in accordance with the mineral resources planning and relevant national regulations. It is prohibited to build high-alumina clay production and processing enterprises in special conservation areas such as drinking water source reservation areas, natural reservation areas, scenic reservation areas, ecological function reservation areas, basic farmland reservation areas, cities and their suburbs, residence, schools and kindergartens, health center, hospitals and perimeter 1 km from enterprises having high requirements on the environment such as food, medicine, electronics etc., the both banks of main rivers and roads, somewhere near trunk railways.
- Q:How much is the duration of fire resistance of the porous brick shale?
- It depends on its formula since the highest temperature varies from formula. For example, the temperature of common bricks is 900℃, if the lime in it accounts for most part, then the temperature could reach 1050℃; if coal ash accounts for over 40%--50%, then the temperature could amount 1050℃--1150℃.
