摘　　要：本文对钒酸钇的相图进行了系统的研究,详细地分析了钒酸钇熔体体系的二元相图、三元相图以及一些中间体系的相图;对比分析了相图对晶体生长的作用．并对用Ｃｚ法生长钒酸钇的过程中出现的黑相进行了物相分析,认为出现黑相的原因是生长过程中钒的变价和挥发造成的．The phase diagram of YVO4 system, including the binary diagram, the ternary diagram and the schematic phase diagram, etc, are investigated in this pape. From the contrasting result, it can be seen that the phase diagrams affect the crystal growth greatly. Analysis of the black phases which occurred in the procession of the crystal growth, indicates that the black phases are caused by V3+ volatilization, which is identical to the literatures.
