This powder is manufactured specifically for polishing sapphire without scratching.  Emphasis has been placed on grain shape during the crushing process, along with a special multi-stage gradation process.  5 lb minimum order.  

This product (B4C-SP F400.5)  has a sizing of 40/12 mkm.  

Please note that this product is different from standard F400 Boron Carbide powders, as well as from F400 B4C for wire saw slicing, so make sure you are ordering the correct item.  If the product item code contains "SWS" it is designed for wire saw slicing.  If you are seeking a boron carbide powder to polish sapphires, please look for a model number that ends with the letters "SP". 

FEPA Gradation, Abrasive Grade.  B+C = 98% minimum.
