Boron Carbide Powder

Boron Carbide is a high performance abrasive material with chemical and physical properties similar to diamonds, such as, chemical resistance and hardness. Therefore it has been given the nickname “Black Diamond”. It is one of the leading grinding materials ranking third after diamond and boron nitride.

Application examples include:

• Grinding, lapping and polishing tungsten carbide and other hard materials such as various types of ceramics, minerals, glasses, etc.
• Metallurgical refractory with high corrosion and oxygen resistance.
• Neutron absorbing materials for nuclear technology.
• Additive for sintering silicon carbide parts and diamond tools.
• Steel modification component with high boron content.

Silicon Carbide Powder

Silicon carbide, also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance.

Application examples include:

• In manufacturing, it is used for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting and sandblasting
• In the arts, silicon carbide is a popular abrasive in modern lapidary due to the durability and low cost of the material
• Car brakes, car clutches
• Ceramic plates in bulletproof vests
• Semiconductor electronics applications that are high-temperature, or high-voltage, or both
• It is used as a support and shelving material in high temperature kilns such as for firing ceramics, glass fusing, or glass casting. Silicon Carbide kiln shelves are considerably lighter and more durable than traditional alumina shelves.
• Particles of silicon carbide are laminated to paper to create sandpapers and the grip tape on skateboards.
