Product Description

Product Description:


Silicon carbide, with a chemical formula of SiC, is a compound comprised of quartz sand, petroleum coke, wood chips and other raw materials. This combination is then smelted in a resistance furnace at high temperatures. It is also commonly referred to as electrolon sand or refractory sand.


There are two types of silicon carbide: black and green. Both are hexagonal crystals with a specific gravity of 3.20~3.25g/cm3. The Mohs hardness of silicon carbide is 9.5, making it an extremely hard material.


The powder form of silicon carbide is obtained through various chemical processes. Green silicon carbide contains more than 99% SiC and is known for its excellent self-sharpening properties. It is mainly used for processing hard alloys, titanium alloys, and optical glass.




  • 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

Cutting: With its exceptional hardness and ability to maintain its sharp edges, black silicon carbide is also widely used as an abrasive material in cutting tools such as saw blades and drill bits. It is especially useful for cutting and shaping hard and brittle materials with precision and accuracy.


Polishing: The fine-grained structure of black silicon carbide, combined with its hardness and durability, makes it a popular choice for polishing and lapping applications. It is commonly used on metals, ceramics, and other materials to achieve a high-quality, mirror-like finish.


Metallurgical Applications: Due to its excellent thermal and chemical properties, black silicon carbide is commonly used in metallurgical applications. It can be found in foundry castings, as well as in iron and steel making and non-ferrous metal production processes.
