98%Sic Grade Black Silicon Carbide 0-5mm1-10mm for Metallurgical Refractory

Product Description

Product Description
Silicon Carbide SIC Description Silicon carbide SIC is a non-metallic mineral product produced from quartz sand (SiO2) and anthracite or petroleum coke (C) as basic raw mat
erials at high temperatures above 1800 degrees Celsius. It has high hardness, small expansion coefficient, brittleness and good thermal condu
ctivity. With its characteristics, it is widely used in abrasive grinding tools, electronic product grinding, refractory materials, special ceramics,
foam ceramics,additive modification of coating plastics, auto parts, military aviation, deoxidizers for steelmaking, etc. The company mainly
produces black silicon carbide and green silicon carbide in various content specifications. Detailed Photos

Product Application

Application Direction	Silicon Carbide	Description
Sandblasting and engraving	black	generally purchase F36, F46, and the content requirement is about 97.5-98%; for export orders, the content requirement is between 98-98.5%. Such materials have hardness and cleanliness requirements.
Grinding wheel and sandpaper	black	generally 46#-90#, the grinding wheel uses F standard; the sandpaper uses P standard.
Brake pads	black	generally use CF500# and CF600# materials.
Furnace wall coating	black	generally uses 97% 325mesh.
Abrasives	Black	Customers purchase products concentrated in coarser grades than F220, with F46, F60, and F80 performing better.

(1) Silicon carbide SIC for refractory materials
During the production and processing of black silicon carbide, a large amount of silicon carbide with a content of less than 90% is formed and
produced, commonly known as low silicon. The main uses of low-content black silicon carbide are deoxidizers, gun mud, castables, and trench
materials in the refractory industry and steelmaking industry. Our company supplies silicon carbide in various specifications. The product cont
ent distribution is: 98%, 95%, 90%, 88%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50% ,45%,40%. The particle size can be customized according
to customer needs, usually 0-1mm, 0-50mm, 1-10mm, 100-400mesh, etc.
(2) Silicon carbide for steelmaking deoxidation and casting
Silicon carbide is a compound composed of carbon and silicon mainly combined by covalent bonds. It is a non-oxidizing material. Because it ex
hibits significant instability in high-temperature oxidizing atmospheres, the oxidation reaction proceeds rapidly especially when the temperatu
re exceeds 1627°C. Its characteristics can be used to replace ferrosilicon and carburizing agents in the process of smelting ordinary carbon steel
and some low alloy steels in converters and electric furnaces to deoxidize, heat and increase silicon and carbon in molten steel to achieve the
purpose of reducing steelmaking costs. , achieved better results. Among them, the most commonly used quality is concentrated at 80%-95%,
and the particle sizes are mainly 0-10mm, 0-5mm, 1-3mm, and 1-5mm (mostly used in casting). Company Profile
