초록
In this paper, cheap mineral materials were used as the base materials of lightweight porous ceramics prepared through foamimpregnation method. The effect of the sintering temperature on the properties of the prepared porous ceramics was studied. The porous ceramic was mainly composed of amorphous silicon oxide, crystalline cordierite and mullite phases, and a smallamount of alumina phase. As the sintering temperature increased, the porosity of porous ceramics gradually decreased from94% to 92%, and the bulk density increased from 0.173 gcm-3 at 1100 ℃ to 0.194 gcm-3 at 1200 ℃. The best sinteringtemperature was 1180 ℃. The porosity of the porous ceramics sintered at 1180 ℃ was 92.14%, the volume weight was 0.189gcm-3, the shrinkage rate was 15.80%, the compressive strength was 0.79 MPa, and the thermal conductivity was 0.295 Wm-1k-1. The lightweight porous ceramic has high porosity, low density and good thermal insulation, as well as low cost, having greatpotential for application in fields such as thermal insulation, adsorption, and environmental protection.
Abstract
