| 内容記述 | Syntheses of emerald were performed by flux method using Pt-crucible and electric furnace. Starting materials are as follows. The principal ingredients are BeO, Al2O3 and SiO2. The coloring reagent is Cr2O3 for green color. The fluxes are MoO3-Li2O and PbO-PbF2. The mole ratio of BeO : Al2O3 : SiO2 is 3 : 1 : 6, which is the composition of beryl. For the total weight of the principal ingredients, the weight % of Cr2O3 were varied between 1.0 and 2.8, and the total weight of fluxes were varied between 1.7 and 3.9 times. The maximum heating temperature was 1,100 ℃ and the maximum heating time was 30 days. Although the beautiful transparent green hexagonal columnar emerald crystals (maximum crystal length for c-axis direction is 2.7 mm) were obtained as informed by Oishi(1994), several kinds of by-products (phenakite, β-LiAlSi2O6, MoO3, and PbAl2Si2O8) were also produced as for some experimental conditions. In this study, we report the crystal data of emerald and some by-products. | |||||
