High Purity Black Silicon Carbide / SIC 90

Product name	Silicon Carbide (Carborundum ) / SiC / Black Silicon Carbide / Green Carbide Silica
Model No	BA-20#
Brand name	BA,CHINA
Description	Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke. 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. 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.
Advantage	1. raw materials are of high quality: pure silicon carbide, guaranteeing the products’ good quality. 2. sharp knife-edge, having cutting function. 3. Centralized and uniform particle size distribution 4. electrical conductivity 5. heat conductivity 6. chemical stability 7. high thermal conductivity, 8. low expansion coefficient 9. good abrasion-resistance
Parameter	· The shape: polygon · Color: black · Proportion:3:2 · Bulk density:1.45-1.56 g/m³ · Mircohardness:2840-3320g/mm² · Mosh hardness: 9.15 · Package: 25\kg · SiO≥92.5% · Free C≤0.3% · Fe2O3≤1.2%
Usage	· Black silicon carbide, sic≥98.5%,its toughness is better than green silicon carbide, mostly for processing low tensile strength of the materials, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.
Shipping way	By sea, by air, by express

If you’ve Silicon Carbide enquiry, please don’t hesitate to let us know. ^_^

Q: What kind of flexible fireproof material is really good?: Flexible waterproof materials mostly are asphalt, linoleum and other organic material, which is also called linoleum coiled material waterproof layer. it uses the linoleum, glass cloth fabric as tire layer coil, using all kinds of cementing material phase of asphalt and so on. Make coil bind on roof structure plate leveling layer to form waterproof layer. Flexible waterproof material has high tensile strength, big elongation and light quality, which is convenient to construct. But it has relatively strict operation technology can resistant penetration and aging resistance than rigid materials, aging. Its life is short. Refers to a kind of waterproof material form relative to the rigid waterproofing materials such as waterproof mortar and waterproof concrete. In the form of its and grassroots attached two categories, it includs waterproof coating and waterproofing materials. According to different paste position of waterproof material, it can be divided into outside waterproof waterproof (outsourcing) and inside waterproof (insourcing waterproof) two kinds. Waterproof coil material must be stuck in the grass-roots that have enough stiffness of the. Before pasting, you should apply leveling layer and waterproof layer should be added protective layer of the outside, and need to make the rotation of the flexible material, the processing of subsequent and head closing, in order to ensure the continuity of the waterproof layer and sealing. In addition, there are all kinds of waterproof material and moistureproof coating material.

Q: Who knows about roof fireproofing materials?: At present, only phenolic foam boards can meet requirements. The test temperature can be 2,000 degrees, and there is no molten droplet during the tests and it can maintain integrity. heat conductivity coefficient: 0.03W / (mk), non-combustible, non-toxic, smokeless!

Q: How to understand qualitative and qualitative refractory materials?: Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.

Q: How many types of special refractories are there?: Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials

Q: Which industry does refractory belong to?: It belongs to construction industry.

Q: How to make fire resistant materials for building stoves: Why Qianjun game protected mode can attack the foreign baby call

Q: What are the fire resistances of grc partition panels?: Light partition walls with keels has the longest fire resistance of 4 hours according to the thickness of the walls.

Q: What are the chemical composition of refractory cement?: Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.

Q: What are the types of steel refractory materials: Large steel ladle usually made with magnesia carbon brick, of course, it contains a intermediate layer (such as good a little high alumina castable), heat insulation layer and heat preservative materials Alumina-magnesia castable is OK for small steel ladle

Q: What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?: You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
