anorthitite

0,there is anorthite phase and little quartz and submellite to separate out; When Si/Al>4.

0时,样品有钙长石晶相和少量的石英与钙黄长石析出;而当Si/Al>4。

The results show that the content, the alteration extent, the average grain size and impurities, fissures of anorthite are the controlling factor of Dushan jade's transparence.

结果认为 :钙长石的含量、蚀变程度、平均颗粒度的大小、杂质的含量和裂隙的发育程度是独山玉透明度的控制因

This paper adopt inorganic salt materials of nitric alumimium and nitric calcium instead of metal alkoxide as precursors,synthesizing the superfine powder anorthite by sol-gel method.

采用无机盐前驱体原料硝酸铝和硝酸钙取代金属醇盐 ,以溶胶凝胶法制备超细钙长石粉末 ,对影响合成的反应温度、浓度、烧成制度、pH值、工艺路线等进行了系统的研究 ,得到比较好的工艺参数。
