有关银星石的矿物学工作,不少学者作过研究,但对其化学式、晶胞参数等有不同看法,对于空间群的判定亦未作详细叙述。本文通过银星石晶体结构的测定认为该矿物属斜方晶系,空间群系 C_(2v)~9-P_((c2)_1n)而非 D_(2h)~(16)-P_(cmn),共化学式为 Al_3(OH)_3(PO_4)_2·6H_2O,每个晶胞中含有四个分子。同时文中也对银星石的物理性质作了较满意的解释。
Many scholars have done some research on the mineralogy of Silver Star Stone, but have different opinions on its chemical formula, unit cell parameters and so on, and have not elaborated on the judgment of space group. According to the determination of the crystal structure of silver star, the mineral is orthorhombic, the space group C_ (2v) ~ 9-P _ ((c2) _1n) instead of D_2h ~ (16) -P_ (cmn) , The common chemical formula is Al_3 (OH) _3 (PO_4) _2 · 6H_2O, each unit contains four molecules. At the same time, the article also made a more satisfactory explanation for the physical properties of Silver Star Stone.
