Successful realization of detonation‐induced h‐BN→c‐BN phase transition requires that a hydrolysis of BN by water from the detonation products is suppressed. For this two kinds of experiments for synthesis of c‐BN were attempted: using benzo‐trifuroxan (with no water in products) as an explosive, in 80% yield; and using the cast 50% TNT+50% RDX charges containing 5–25 wt.‐% of h‐BN powder in order to expend water from the detonation products by a part of BN, and to realize the phase transition in the rest, in 10% yield.
