| Black Silicon Carbide Introduction Because of the rarity of natural moissanite, most silicon carbide is synthetic. It is used as an abrasive, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 °C (2,910 °F) and 2,500 °C (4,530 °F). Fine SiO2 particles in plant material (e.g. rice husks) can be converted to SiC by heating in the excess carbon from the organic material. The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating with graphite at 1,500 °C (2,730 °F). |
We provide silicon carbide with varying contents from 98% to 40%, allowing for customization based on customer requirements. The particle size can also be customized, typically ranging from 0-1mm, 0-50mm, 1-10mm, to 100-400mesh ect .

(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).
