1.Structure of Zircon Sand and Zircon Powder
We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %. We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %. Zircon is a remarkable mineral, if only for its almost ubiquitous presence in the crust of Earth. It occurs in igneous rocks as primary crystallization products, in metamorphic rocks and in sedimentary rocks as detrital grains.
Further, the mineral due to hardness, durability and chemical inertness, zircon persists in sedimentary deposits and is a common constituent of most sands.
2.Main Features of Zircon Sand and Zircon Powder
The zircon sand is mineral mainly containing ZrSiO4.
The pure zircon sand is a kind of colorless and transparent crystal and shows different colors such as
yellow, orange, red and brown due to different origins, types of impurities and content, and also coexists in
beach sand with ilmenite, rutile, monazite,etc. the zircon sand can be separated benificiation process.
3.Main usage of Zircon Sand and Zircon Powder
Shell moulds and cores for casting gray, Malleable and nodular cast iron, alloyed steel and carbon steel, non-ferrous metals, etc

- Q:How to deiron refractory?
- It cannot be done in conventional approaches, because you are referring to refractories. If using acid liquor soaking method to deiron, the material itself will be also damaged! If just for reducing the corrosion of materials, it will be OK to add a corrosion-resistant and fireproof protection layer.
- Q:What is refractory aggregate?
- Refractory aggregate is fire-resistant product improved with low temperature binder, chemical?compound and normal temperature strength.
- Q:It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
- The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
- Q:What high-molecular polymers can be used as fire-resistant material binder?
- Melamine resin should be compounded with fire-resistant material and acrylic acid material is easy to burn. But high-molecular polymers can be used along with the above two. Polysulfone is featured by heat resistance and high temperature resistance. Polyurethane is difficult to process and compound with fire-resistant material. Phenolic resin is not easy to burn. Epoxy is expensive and self-extinguishing once away from fire.
- Q:How many refractories are there for boiler above 1200 ℃？
- Ordinary clay brick is for burning layer, red brick for external wall, light clay brick for thermal insulation layer, built by clay refractory mortar. Sindeyuan Refractories.Hope you adopt. Thank you. In fact, there are many manufacturers producing furnace burden. We has been using products of Huaheng, which are anti-erosion, easy to construct and can improve production efficiency, reduce steelmaking cost.
- Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
- the fire resistant level of aerated concrete building blocks can reach the grade one level. Aerated concrete strength grade shall be divided according to the concrete cubic compressive strength value. Use the symbol C and the cube compressive strength value (in N / mm2 or MPa gauge) to express. According to GB50010-2002 "concrete structure design specifications" provisions, ordinary concrete is divided into fourteen levels, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 .
- Q:what kind of fireproof materials is used for high rise buildings?
- steel is recommended As a form of high-rise building structure, steel is widely used especially in the ultra-high-rise and long span construction showing strong vitality, for its high strength, light weight, and good extensibility, resistance to shock and short construction period. The mechanical strength of steel decreases with rising temperature at about 5000 ℃, decreasing about 40%-50%. the mechanical properties of steel, such as yield points, compressive strength, elastic modulus, and load capabilities have declined rapidly , quickly losing their ability to support, leading to building collapse. Therefore, it is imperative to protect steel structures. Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities.
- Q:What are included in wall fireproofing material?
- External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake.
- Q:Development trend of refractories
- Mullite Matrix clinker. There are higher requirements of kaolin and refractory annded life, it should be able to grind medical industrial raw materials alumina, vacuum extrusion molding, high temperature roasting and smelting from unshaped refractory material a good thermal mechanical properties in the kiln and has good application prospect; 2, Dong Qingshi clinker. With kaolin and magnesia as raw materials, wet grinding, vacuum extrusion, and then high temperature calcination, furniture has a very good prospect; 3, magnesium calcium sand. Because of the development of clean steel, low carbon steel, high oxygen steel and stainless steel, the basic importance of free calcium oxide refractories is supported; 4, fused eutectic composite. Bauxite based fused corundum, bauxite based fused mullite, bauxite based fused mullite zirconia, fused corundum zirconia fused zirconia, Magnesium Oxide and other materials have been developing rapidly; 5, high density spherical hollow mullite aggregate. The wall thickness of the shell of the 0.2 - 1.5 - 5 mm, diameter 40 mm, smooth surface, can not be uniform, spherical shell, this may be a double, a prominent part of the surface can be dense, can also be used for hollow casting material, not only can improve the insulation performance of the material, in order to reduce the volume density. Instead of destroying its strength.
- Q:On the problem of making refractory materials
- But if only a is chosen, does it mean that as long as it is insoluble in water, it can be made of refractory material? Obviously absurd!
