摘要
本文利用燃烧氧弹制备了结晶度小、缺陷多、活性较高的β－２ＣａＯ·ＳｉＯ２，同时测得其标准生成焓为－２３１７．０ｋＪ／ｍｏｌ．从β－２ＣａＯ·ＳｉＯ２的粉晶ＸＲＤ分析结果可得其晶胞参数ａ＝０．５５１８ｎｍ，ｂ＝０．６７９０ｎｍ，ｃ＝０．９３３０ｎｍ，β＝９４．
By means of the combustion bomb β 2CaO·SiO 2 has formed with lower crystallinity, more defects and higher reactivity in this paper. Its standard enthalpy of formation is determined to be -2 317 0 kJ/mol. Cell parameters which are a =0 551 8 nm, b =0 679 0 nm, c =0 933 0 nm, β =94 47° have been gained from XRD of powder β 2CaO·SiO 2.
