    Abstract
  • It is well known that Li3N, Mg3N2 and Ca3N2 are catalysts for cBN synthesis under high temperature and high pressure. We discovered that they could also act as catalysts for hBN formation at high temperature and normal pressure. It is confirmed that, from a series comparative experiments, each of them has catalysts effect only on melting condition, the catalytic order for hBN formation is Li3NMg3N2Ca3N2, which is similar to that for cBN synthesis. The suggestion that a catalyst for hBN formation may also be a catalyst for cBN synthesis may be reliable.
