摘要：

Wetting behavior of BaB2O4 on substrates of graphite; Si3N4, BN, AlN and Pt was measured using the growing melt drop method so as to identify a possible crucible material for use in growing crystals by the Bridgman method. The relationship of the magnitude of the contact angles between the melts and the substrates was as follows: graphite > Si3N4 > BN > AlN > Pt. When the contact angle was large, supercooling was small. Superheating was necessary to obtain the low-temperature single phase BaB2O4 except when using a Pt crucible. Si3N4 and BN were the best suitable crucible materials.
