摘要
提出了用粉煤灰制取活性ＳｉＯ＿２的方法及工艺，对碱熔机理进行了探讨，并通过试验找出了碱熔过程最佳工艺条件；同时，对影响产品质量的因素进行了分析，提出了提高产品质量的方法。
The method and technological process for making active SiO2 from ground coal asheswas proposed,the mechanism of alkali fusion was approached;the optimum technical condition ofalkali fusion was found by exporiments,The factors which affect the production quality were aisoanalyzed,and a method of improving the production quality was put forward.Products of highquality were obtained through the exporiments,and a new field of comprehensive utilization forground coal ashes and preduction of active SiO2 were developed.
