Boron Carbide and Silicon Carbide Powders and Compounds

Boron Carbide (B4C) Powder from Advanced Abrasives with a Mohs hardness of 9.5 is almost as hard as cubic boron nitride (cBN) and so serves as a lower cost alternative abrasive to both diamond and to cBN. The closely controlled grading and particle shape of this powder results in high cutting rates and a uniform finish.

Also available as Boron Carbide Compound, the powder is presented in a grease based carrier. Boron carbide powders and compounds are available in multiple abrasive grit size choices from F10/30 to F1500 and are suitable for the precision lapping and polishing of many engineering materials.

Advanced Abrasives’ Black Silicon Carbide Powder is water-classified to exact specifications. Controlled grading and precise particle shape provides uniform finishes and high cutting rates. It is provided in multiple abrasive grit sizes from F80/100 to F1200 and is used for pressure blasting, bonded and coated abrasive products, sawing quartz, and precision lapping and polishing.

PremaSol Silicon Carbide Compound is produced from silicon carbide powder in a choice of base carriers (universal-based, oil-based or water-based). Closely controlled grading and particle shape ensures high cutting rates and a uniform finish. Available in multiple abrasive sizes ranging from 1 to 80µm and is typically used for the precision lapping of ceramic and metal sealing faces.
