1.Structure of Silicon Carbide Description
Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke.
Black silicon carbide is typically used for working on cast iron ,non-ferrous metals, stone, leather, rubber, and other materials which requires sharp cutting characteristics. The mineral is also used widely as a refractory material and metallurgical additive.
2.Main Features of the Calcined Bauxite
Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and has a certain degree of electrical and heat conductivity.
3.Main usage of the Calcined Bauxite
1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials

- Q: What are unshaped fire-resisitance materials?
- Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
- Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- Mechanism analysis of silicon actionWhen silica fume is added to the carbon composite refractory, the phase changes and chemical changes are as follows:<1> Si (s) +C (s) =SiC (s) Delta G ~ =-522+1.50T (kJ)<2> Si (s) +MgO (s) =Si (g) +Mg (g) Delta G ~ =203.9-0.13T (kJ)<3> 2Si (s) +CO (g) =SiC (s) +SiO (g) Delta G ~ =-963.2+0.31T (kJ)<4> SiC (s) +CO (g) =SiO (g) +2C (s) Delta G ~ =81.47-0.15T (kJ)<5> SiO (g) +CO (g) =SiO2 (s) +C (s) Delta G ~ =-668.8+0.33T (kJ)From the above diagram and the reactions seen at high temperatures has joined the Si SiO and Mg volatiles, but <4> and <5> reaction have played a role in inhibiting carbon oxidation, and the condensation of SiO2 to a certain extent the role of protective film.The total reaction process is CO reduction to C, and there is a certain volume expansion, so that the pores are blocked and the density of bricks is increased. Therefore, the oxidation resistance of brick is improved.
- Q: What is the difference in the nature between the refractory material and thermal?insulation?material
- thermal?insulation?material is a material which has a strong impedance to the heat flow. the nature of the material requires that the material can isolate the delivery of thermal, and the low heat conductivity coefficient and expansion coefficient of the non-metal material.refractory is good in heat resisitance and chamical erosion but not high temperature resistance. Requirements on nature is still in high temperature.
- Q: I know which material is the fire resistance rolling shutter door
- the materials of fire resistance rolling shutter door are: the inner of fire resistance rolling shutter door is generally filled with aluminum silicate fiber cotton. fire resistance rolling shutter door is divided into AAA inorganic fireproof rolling shutter door and steel fire resistance rolling shutter door. the fireproof?performance of inorganic fireproof rolling shutter door is better, but steel fire resistance rolling shutter door has a certain wind load resistance, which can be installed outdoors.
- Q: Is there vermiculite in refractory?
- Vermiculite is usually used as lightweight material in refractory field, and its volume density is about 0.5.
- Q: What is the material composition of the new fire-resistant coating?
- The basic composition of thick coating steel structure fire is: Binder (Portland cement, magnesium oxychloride or inorganic high-temperature bonding agent), aggregate (expanded vermiculite, perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifiers , hardening agent, waterproofing agent) and water. Fireproof coating binders Portland cement, magnesium oxychloride cement and an inorganic binder of the fire-resistant coating for steel structure base material. The conventional inorganic binder include alkali metal silicates and phosphates substances.
- Q: Which brand of AAA refractory is good?
- Foshan Nanhai Yanbu Shuying fire-resistant insulation material is very good, and it is a professional company of the production and sale of refractories. Our company specializes in the production of refractory bricks, refractory bricks, refractory castable, refractory aggregate, refractory materials, bauxite, alumina bricks and to undertake the production of various common refractory bricks and non-sizing bricks. The Zhengzhou Fire High Temperature Materials Co., Ltd. is also a good company. It is a collection of R & D and production company. The company mainly produces refractories, refractory bricks, refractory castable, refractory aggregate, refractory materials, special refractory bricks.
- Q: how is the high-temperature flame-retardant fibre board?
- high-temperature flame-retardant fibre board is good decorative material. Hope it helps you.
- Q: what needs to be noted when choosing and using blast furnace fireproof materials?
- it depends on the size of the blast furnace. below 200 cubic meters alumina bricks and carbon brickcan be used. 200 cubic meters and above are currently integrated bottom, not the same as the size of the cubic level, varying in the use of refactory. I hope my answers above are helpful to you and your ideal anwers.
- Q: Can anyone tell me what is a high alumina refractory?
- Refractories refer to a class of inorganic non-metallic materials whose refractoriness are no less than 1580 ℃. Refractoriness is the Celsius temperature when cone-shaped samples can resist high temperature without softening and melting down in the absence of a load. But it is not accurate to define refractory merely by judging that whether the refractoriness is no less than 1580 ℃. Currently, the materials whose physical and chemical properties allow them to be used in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and so on, among which the metallurgical industry is the largest demander in this regard, accounting for 50% to 60% of total output. Hope it will help you out!
