Abstract
PURPOSE: In high temperature, high pressure transformation of hexagonal BN to cubid BN, fluoride such as (NH4)2SiF6 is added as catalyst, thereby effecting the reduction of synthetic pressure and temperature and the production of powder cubic BN solely consisting of tetrahedral crystal.
CONSTITUTION: Hexagonal BN is subjected to high temperature and high pressure under the condition shown as black dots in the figure, whereby fluoride such as (NH4)2SiF6 and ZnF2 is added as catalyst. The resulted cubic BN is fine powder 0.5 to 10μm in size and solely comprises tetrahedral crystal, and as such well suited for abrasion and cutting grains.
