About Silicon Carbide. Silicon Carbide is a semiconductor widely used as an abrasive. It is synthetically produced in mass since 1893 and its natural form was only observed in 1905. The transparent mineral known as moissanite is almost as brilliant and as hard as diamond and is therefore often used as a gemstone.

Silicon Carbide is synthesized from silicon dioxide and carbon. The quality and output of Silicon Carbide hinge on the purity of its raw materials, necessitating the utilization of high-purity sources like natural silica sand or ground quartz, with high-SiO2 content, ideally surpassing 99.7%. Low-ash petroleum coke stands out as the favored carbon source. Although charcoal and anthracite serve as alternatives, they lack the purity essential for high-grade SiC production, particularly green SiC.

The Acheson process, using rectangular cross-section electrical resistance furnaces, is the traditional method of production, but newer methods like the ESK-SIC process aim to reduce waste gas emissions. The Lely process remains in use, especially for high-purity Silicon Carbide. There has been a significant production shift from Europe and North America to China and South America, primarily due to escalating energy expenses.

Silicon Carbide Handling. Silicon Carbide requires storage in a tightly sealed, isolated, and dry environment, particularly in its powdered form, as it readily absorbs moisture from the surrounding air. Typically, the material is transported in either 1000 kg big bags or 25 kg bags, ensuring secure handling and preservation of its properties during transit.

Silicon Carbide Production. Raw materials and the respective production processes employed in the manufacturing of Silicon Carbide are listed below.

  • Green/anthracite sponge coke + quartz (Acheson electrothermal process)

Silicon Carbide Uses. The uses and applications of Silicon Carbide may vary according to its specification. The main forms of Silicon Carbide are sintered silicon carbide (SSC); nitride bonded silicon carbide (NBSC); and reaction bonded silicon carbide (RBSC). Silicon Carbide can also vary in terms of particle size, ranging from the 10 mm scale for refractory sand down to 10,000 mesh for ultra-fine powder for abrasion and polishing.
