Product Description

Product Description:

Black Carborundum Silicon Carbide High Purity Top Grade Products


Silicon carbide, with the chemical formula SiC, is a compound made up of quartz sand, petroleum coke (or coal coke), wood chips (with added salt for producing green silicon carbide), and other raw materials. It is then heated at high temperatures in a resistance furnace, a process known as smelting. Silicon carbide is also commonly referred to as electrolon sand or refractory sand.


This compound is categorized into two types: black silicon carbide and green silicon carbide. Both varieties have a hexagonal crystal structure and a specific gravity of 3.20~3.25g/cm3. Additionally, silicon carbide has an impressive Mohs hardness of 9.5. The production of silicon carbide powder involves various chemical processes. 



  • Suitable for use as a silicon carbide seal
  • High purity, single crystal silicon carbide
  • Stable and durable, ideal for use in silicon carbide mechanical seals
  • Can be used as a silicon carbide pump seal

Metallurgical Applications:

Black silicon carbide is widely used in metallurgical applications, playing a crucial role in foundry castings, iron and steel making, and non-ferrous metal production. Its high thermal conductivity and low thermal expansion make it a valuable component in these industries.


Refractory Materials:

One of the main uses of black silicon carbide is in the production of refractory materials, including kiln furniture, crucibles, and furnace linings. Its chemical inertness and high-temperature stability make it an essential ingredient in these critical applications.


Composite Materials:

Due to its exceptional strength and wear resistance, black silicon carbide is often used as a reinforcement material in composite materials. It is commonly found in aerospace components and brake pads, providing toughness and durability to these high-performance products.
