- Abstract
Lightweight mullite aggregates were prepared with cyanite fine powder as the main raw material, walnut shell powder as the pore forming agent, and silica sol as the binder. Effects of calcination temperatures (1 300,1 400, 1500, and 1 600 °C for 180 min) and holding times (1500 °C for 60, 120, and 180 min) on the bulk density, apparent porosity, linear change rate on heating, phase composition, and microstructure of lightweight mullite aggregates were investigated. The results show that the sample insulated at 1500 °C for 60 min exhibits the optimum comprehensive properties, with bulk density of 1. 18 g.cm³, apparent porosity of 59.8%, linear change rate on heating of 2.58%, and mullite content of 86 mass%.
