Abstract:

The chemistry of the strontium borates has been studied, and a new ferroelectric strontium borate hydrate 2SrO.3B2O3.5H2O has been synthesized. This compound is the strontium isomorph of cole manite 2CaO.3B2O3.5H2O. The following series of reactions were investigated 1 reactions of borax and strontium iodate, 2 miscellaneous conversion reactions in borax and boric acid solution, 3 reactions of ammonium pentaborate and strontium nitrate, and 4 reactions of ammonium pentaborate and strontium iodate. Five compounds produced by the above reactions were compound I 2SrO.3B2O3.5H2O, compound II SrO.I2O5.O.5H2O, compound III SrO.3B2O3.4H2O, compound IV SrO.3B2O3.4H2O, compound V SrO.B2O3.4H2O. Compound VI SrO.B2O3.4H2O was prepared by other methods. Compound III is dimorphous with compound IV compound V is dimorphous with compound VI. Author
