A great deal of examples of 205 oxyacid salts, some complex silicate mineralsand a few salts under high temperatures, their heats of formation have been cal-culated by this simplified formula in order to ascertain their heats of formation,the results obtained agree well with experiments. The thermal stability and decomposition temperature, T_d, of oxyacid salts havealso been briefly discussed. 收稿日期: 1979-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 温元凯 邵俊 王三山 陈德炜 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I1/98 [1] Rossini, F.
