摘要
利用伊利石粘土岩，混入一定配比添加物焙烧后，含钾矿物伊利石和正长石转变为焙烧产生的新矿物相──钾霞石。鉴于钾霞石的结构易于在酸溶液中破坏，经酸浸、氨水中和、蒸发可制得含Ｎ１１．４６％，Ｋ２Ｏ８．７８％的氨钾肥。
After baking the illite claystone with a certain proportion of additive, the kaliteand kaliorthoklas will be transferred into the kaliophilite which is a new mineral formed inthe process of baking. Since the texture of the kaliophilite could be destroyed easily in theacid solution, the nitrogenous and kalious fertilizer, with 11. 46% of N and 8. 78% of K2O,can be made from the kaliophilite.
