Title: Method for synthesizing boron nitride
Inventor: YATSU SHIYUUJI
IPC: B01J3/06
Filed: 1983-12-16
Abstract: PURPOSE:To synthesize a large-sized single crystal of cubic BN with high reproducibility by bringing BN as a starting material and a single crystal of cubic BN as a seed crystal into contact with a flux contg. a proper amount of BN and by heating the whole reaction system under proper temp. conditions. CONSTITUTION:A flux is prepd. by adding cubic BN (CBN) and BN to a mixture of one or more kinds of boronitrides of alkali metals or alkaline earth metals. The amount of the BN added is between 0.5mol% and an amount enough to provide a eutectic composition to the boronitrides. BN as a starting material and a single crystal of CBN as a seed crystal are brought into contact with the flux at separate positions. The whole reaction system is then held at the m.p. of the flux or above under pressure and temp. conditions under which CBN is stable, and the temp. of the seed crystal part is kept relatively lower than the temp. of the contact surface between the starting material and the flux. The melting of the seed crystal is prevented, and a large-sized single crystal of CBN is grown on the seed crystal.
