Meantime, the study of the modification of calcium bentonite was made.
同时，对钙基膨润土人工钠化进行了研究。
The results show that sodium bentonite can greatly improve the drop strength and compressive strength of green pellets, while calcium bentonite could enhance shock temperature of green pellets.
结果表明，钠基膨润土能使生球落下强度、抗压强度显著提高；而钙基膨润土在改善球团爆裂温度方面优于钠基膨润土。
Through microscopic analysis of XRD and infrared spectra, when calcium ion is replaced by lithium ion, the lattice spacing of bentonite and the water molecule number in the structure decrease.
经xrd和红外光谱的微观分析，当锂离子置换钙离子后，膨润土的晶格间距减小，结构中的水分子减少。
