综合介绍了利用助剂分解钾长石的研究现状.通过热力学计算预测以碳酸钠、碳酸钾为助剂分解钾长石的分解反应温度在800～890℃之间.分解反应机理的分析表明:随着焙烧温度的升高,钾长石由单一的焙烧分解状态进入分解和烧结同时进行的状态.实验表明:钾长石矿的分解率达98%以上,以碳酸钠、碳酸钾为助剂在820～850℃即可使钾长石分解.

Advances on thermal decomposition of potassium feldspar with flux agents are reviewed.Thermodynamic calculation shows that the temperature range of the thermal decomposition of potassium feldspar is 800-890 ℃ with stoichiometric additive of sodium carbonate or potassium carbonate.Analysis on the mechanism of thermal decomposition reaction shows that with increasing the calcination temperature,potassium feldspar passes through a stage predominated by single decomposition entering that predominated by decomposition and sinter simultaneously.Decomposition proportions of various potassium feldspar powder materials determined are over 98%.This shows that with stoichiometric additive of sodium carbonate or potassium carbonate,the potassium feldspar can be decomposed at 820-850 ℃.
