摘要：

Solution‐melts based on PbF2—B2O3 and Bi2O3—B2O3 were used in studying the stability regions and for growth, by way of spontaneous crystallization, of crystals up to 3 mm in size of twelve compounds having the general formula RGa3(BO3)4. All of these compounds are isostructural with carbonate mineral huntite. Their composition is highly dependent on that of the crystallization medium. The facing of the crystals is characterized by a small number of simple forms {1011}, {1120}, {2110}, and less frequently {0221}, {0112}, {4041}. The examined parameters include the IR spectra, luminescence spectra, heat of formation from oxides, harness (6 to 8 units on the Mohs scale) and others. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co.
