摘要
首次用K_2O·2SiO_2(KS_2)或K_2O·3SiO_2(KS_3)与KOH、水进行蒸压反应合成纯K_2O·2SiO_2·H_2O(KS_2H),进行了单晶结构分析、粉末衍射数据的采集和精化,给出了精化的晶胞参数和指标化的粉晶衍射数据.KS_2H在360℃脱去其结晶水,约于650℃转化为KS_2晶体.
Pure KS_2H was synthesized for the first time through autoclaving of KS_2or KS_3with KOH and water. The single crystal structure analysis and X-ray powder data collection and refinement were carried out. The well-refined and indexed powder data as well as cell dimensions are given. KS_2H loses its structure water at 360℃ and changes to crystalline KS_2at about 650℃.
