利用钾长石热分解制钾硅复合肥研究
Study on the Preparation of Silicon-K Fertilizer by Using Thermal Decomposition of K-feldspar
摘要
Abstract
[Objective] The aim was to study the preparation of Silicon-K fertilizer by using Silicon-K fertilizer. [ Method ] With calcinationmethods, the effects of material ratio,calcination temperature, reaction time and addition level of Na2SO4 on the potassium recovery of K-feld-spar were systemieally studied. [ Result ] The results show that the optimum reaction conditions were determined as follows K-feldspar: CaS04:CaCO3= 1:1:14,3% NaSO4,l 050 ℃ , 2.0 h. [Conclusion] This sludy showed ihe feasible to manufacture Silicon-K fertilizer by calciningk-felrlspar.关键词
