应用高温拉曼光谱研究了PbMoO4熔体中的生长基元.通过对不同温度下PbMoO4晶体拉曼光谱和熔点温度附近熔体高温拉曼光谱的研究,发现PbMoO4熔体中存在Pb2+阳离子和[MoO4]2-阴离子生长基元.进一步讨论了PbMoO4晶体生长基元和各个低指数晶面间的相互作用,解释了晶体的生长习性和枝晶生长的原因,并指出:PbMoO4晶体生长的最佳籽晶取向是平行于其{101}面所围成的棱锥表面的方向.
The Raman spectra of PbMoO4 crystals at different temperatures and Raman spectra of the melt near the melting point show that the PbMoO4 melts have Pb2 + cations and [MoO4 ] 2-anions. The interactions between the growth motifs of PbMoO4 and the low-index planes are further discussed. The growth habit of the crystals and the reasons for the dendrite growth are explained. The best seed of PbMoO4 crystal growth Orientation is parallel to the surface of the pyramid surrounded by its {101} face.
