无机助剂对钾长石、磷石膏和碳酸钙体系分解温度的影响
The effect of inorganic aids on the decomposition temperature of system consisting of potash feldspar,phosphogypsum and calcium carbonate
【摘要】 以钾长石、磷石膏和碳酸钙作为原料,配料摩尔比例按照n(KAlSi3O8)∶n(CaSO·42H2O)∶n(CaCO3)=2∶1∶6,并利用DTA差热分析仪,研究了几种无机助剂对钾长石、磷石膏和碳酸钙反应体系分解温度的影响。研究结果表明,NaF对该体系有积极作用。
【Abstract】 On the raw material system consisting of potassium feldspar, phosphogypsum and calcium carbonate with the mole proportion n(KAlSi3O8)∶n(CaSO4·2H2O)∶n(CaCO3)= 2∶1∶6,the effects of several inorganic aids on the above-mentioned system decomposition temperatures are studied by using differential thermal analyzer (DTA). The results show that NaF has a positive role.
