摘要：

Red and transparent ruby crystals have been successfully grown by a evaporation method of A(2)O (A = Na, K) - MoO3 fluxes. The grown crystals were up to 3.4 x 2.2 mm in size. The evaporation loss of the fluxes (A(2)O + MoO3) decreased linearly with an increase in the amount of A(2)O when the holding time was fixed at 5 h. As a result, relatively large crystals were grown from the A(2)O-MoO3 fluxes as compared with the solo MoO3 flux (max. 1.8 x 1.7 mm), because time to grow crystals could be lengthened. The influence of a variety of A(2)O On ruby crystal growth was hardly observed in our study. The basic form of the ruby crystals was a hexagonal bipyramid bounded by twelve well-developed [1123] faces, and showed the peculiar shape to the MoO3 system fluxes.
