Metastable phase formation and memory effects in barium borate glasses.

BaB4O7 glass crystallises to different polymorphs of the same composition depending on the prior thermal history of the glass and the surface area of the sample. This indicates...四硼酸钡（BaB4O7）玻璃可根据其先前的热历史与样品的表面积，结晶得到同一化学组成的不同多晶型。这表明……
