Abstract—

This paper presents results of firing of bentonite clay, refractory clay, and metakaolin materials with NaCl additions using convective and microwave heating. Phase structures of microwave-sintered aluminosilicates have been examined and the formation of a nanometer-scale aluminosilicate structure has been demonstrated. The microwave-fired materials have been found to have an increased strength. The mineralogical composition of clay has been shown to influence the microwave sintering behavior of aluminosilicates. Kaolinite and kaolinite-based materials exhibit increased activity in the temperature range 450–550°C during microwave sintering. The role of NaCl as a mineralizing salt has been found out.

粘土矿物组成对铝硅酸盐微波烧结的影响

摘要-

本文介绍了使用对流和微波加热烧成膨润土,耐火粘土和偏高岭土材料并添加氯化钠的结果。已经研究了微波烧结的铝硅酸盐的相结构,并且已经证明了纳米级铝硅酸盐结构的形成。已经发现用微波烧制的材料具有增加的强度。粘土的矿物学组成已显示出会影响铝硅酸盐的微波烧结行为。高岭石和高岭石基材料在微波烧结过程中在450–550°C的温度范围内表现出更高的活性。已经发现NaCl作为矿化盐的作用。
