AGHTH - Heat Treated (roasted above 1350°C)

The Brown Aluminium Oxide grains are heat treated and roasted above 1350°C in order to give more toughness and durability of the grains . It also removes the cracks and gives the blocky structure with high bulk density. It is tougher than AGHTL grains and lasts long but costlier than AGHTL.
