结果表明:矿化剂的加入有利亍石英转化为α-方石英,在煅烧温度为1200℃,保温时间3h,原料粒度相同的情况下,矿化剂NaOH更有利亍石英向α-方石英的转化。关键词:α-方石英;矿化剂;XRD测试技术中图分类号:文献标识码:文章编号:1001-9677(2013)19-0049-03TD985AComparativeStudyofNaClandNaOHontheEffectofCrystalShap...
2013NaCl 和 NaOH 对石英晶型转化的作用效果对比研究*刘莉, 马宏相, 吕剑明( 贵州大学化学与化工学院, 贵州贵阳550003)摘要: 利用石英粉为主要原料, 以氯化钠( NaCl) 和氢氧化钠( NaOH) 分别作为矿化剂合成 α- 方石英, 探讨矿化剂的作用机理及其对石英晶型转化的影响。 采用 X 射线衍射仪表征合成样品的...
All other conditions being equal, the addition of NaCl produces micelles with an aggregation number one order of magnitude larger than the NaOH addition. This is due to the increase of the effective charge per micellized head group produced by the reaction of OH- with the hydrolized head ...
