Boron Carbide is high performance abrasive material with chemical and physical properties similar to diamonds, such as, chemical resistance and hardness. Boron Carbide’s extra hardness gives it the nickname “Black Diamond” (it ranks third after Diamond and Boron Nitride) and is one of the leading grinding materials.
Application Specifics
● Wire Saw Slicing
Our B4C-SWS Boron Carbide Powder specifically developed to deliver the optimum performance and excellent process control in wire saw slicing of the Sapphire products. Starting with chemistry of the raw materials and continue through every manufacturing step: furnacing, crushing, chemical cleansing, crushing (with grain shaping emphasis), and multi-stage grading process every effort is made to insure proper powder performance.
