摘要

在Cs2O - B2O3 - sio2体系中，通过固相反应得到了化学计量比为Cs2O: B2O3: SiO2-1: 3:2 （CsSiB3O7）和1.25:2.5:2的样品。研究了硼硅酸铯СsSiB3O7的相形成。在化学计量比为1:3:2的样品中，CsSiB3O7在680℃时与钾辉石和CsB3O5杂质结晶。在750℃时，观察到熔解形成立方硼硅硅矿CsBSi2O6。在非化学计量组成的样品中，Cs2B4SiO9与CsB3O5在680℃时结晶。当温度升高到750℃时，只会形成硼铝榴石。

Study of the Processes of Non-Stoichiometric Compositions Based on CsSiB3O7

In the Cs₂O–B₂O₃–SiO₂ system, samples with different stoichiometric ratios of Cs₂O : B₂O₃ : SiO₂—1 : 3 : 2 (CsSiB₃O₇) and 1.25 : 2.5 : 2—were obtained by solid-phase reactions. The phase formation of cesium borosilicate СsSiB₃O₇ was studied. In samples with a stoichiometric ratio of 1 : 3 : 2, CsSiB₃O₇ crystallizes with impurities of kirchhoffite and CsB₃O₅ at 680°C. At 750°C, melting is observed with the formation of cubic boropollucite CsBSi₂O₆. In samples of nonstoichiometric composition, Cs₂B₄SiO₉ crystallizes at 680°C along with CsB₃O₅. With an increase in temperature to 750°C, only boropollucite is formed.
