It is one kind of Brown Aluminium Oxide grains with blocky grain shape and high bulk density. To get this kind of product, we calcine the regular grains at a high temperature to give a blue colour,
the purpose is to renovate the crack on the surface and interior of crystal and then to improve the toughness and durability of the grains. bob/Sales manager free to contact me by bob#ascentsun.com
