Crystallization process of molten Ba(B 0.9 Al 0.1 ) 2 O 4 from supercooled pendant drop was investigated on a viewpoint of a supercooling and a solid phase formation. Molten pendant drop was crystallized by a rod touching at an crystallization temperature under an adequate degree of supercooling. Three kinds of rods were used. Each rod was made of Pt, hBN and graphite which had different wettability to the molten drop. There were three kinds of phases on a solid Ba(B 0.9 Al 0.1 ) 2 O 4 , such as a high temperature crystal phase, a low temperature crystal phase and a glass phase. All phases could be formed by the present method.
