The insulating ceramic plate was sintered and surface-decorated using molybdenum tailings as the main raw material (55%) with kaolin, red sludge, feldspar, glass powder and blowing agent incorporated. The water absorption, bulk density, compressive strength and thermal conductivity of the insulating ceramic plate were measured, and the microstructure was observed and the pore diameter was counted. The effects of firing temperature, slurry fineness and addition of blowing agent on the pore size of insulating ceramic plates were studied. The results show that the addition of blowing agent has the most significant influence on the pore structure, pore size and distribution of the insulating ceramic plate, and is the key to obtain low thermal conductivity. In this study, the prepared molybdenum mine tailings-based insulating ceramic plate has high solid content, excellent thermal insulation performance and light weight, and is surely a new building insulation material with broad market prospects.
