CsAlSi2O6、CsAlGe2O6、CsFeSi2O6、CsFeGe2O6 和 CsBSi2O6 通过 Cs2CO3 与氧化物反应并通过碱交换法制备。通过光学检查和X射线衍射对化合物进行了表征。立方硅酸盐铯榴石的线性热膨胀的膨胀测量给出了相对较低的系数，但锗酸盐类似物的膨胀要高得多。简要介绍了CsCrSi2O6和CsCrGe2O6的合成尝试以及CsBSi2O6的特殊性质。
CsAlSi2O6, CsAlGe2O6, CsFeSi2O6, CsFeGe2O6, and CsBSi2O6 were prepared by reaction of Cs2CO3 and oxides and by a base-exchange method. The compounds were characterized by optical examination and X-ray diffraction. Dilatometric measurements of the linear thermal expansions of the cubic silicate pollucites gave relatively low coefficients, but the expansion of the germanate analogs is considerably higher. Attempts at synthesis of CsCrSi2O6 and CsCrGe2O6 and the special nature of CsBSi2O6 are briefly described.
