Some important conclusions were drawn as follows: phase transformation for pyrophyllite was undergone 4 stages, including pyrophyllite stage (indoor temperature to 662 ℃), pyrophyllite anhydride stage (662 to 1 100 ℃),amorphous SiO_2 and mullite crystallite forming stage (1 100 to 1 200 ℃), and coexistence stage of mull.
结果表明,叶蜡石的高温相转变经历了4 个阶段:叶蜡石阶段(室温~662 ℃),偏叶蜡石阶段(662~1 100 ℃),不定形SiO2 与莫来石形成阶段(1 100~1 200 ℃)和莫来石与方石英共存阶段(1 300 ℃~)。
, the pyrophyllite stage(indoor temperature660℃),pyrophyllite anhydride stage(6601 100℃),amorphous SiO_(2) and mullite crystallite forming stage(1 1001 200℃), and.
根据主要物相及其变化和组合特征,可以将叶蜡石的加热相变过程分为4 个阶段,即叶蜡石阶段(室温~660℃)、偏叶蜡石阶段(660~1 100℃)、不定形SiO2与莫来石形成阶段(1 100~1 200℃)、莫来石与方石英共存阶段(≥1 300℃)。
