Abstract: Porous ceramic materials have excellent properties, such as high porosity, good thermal insulation and high temperature resistance, which can be used to effectively reduce heat loss and play a constructive role in energy saving and consumption reduction as lining or insulation layer for industrial furnaces．However, at present, porous ceramic materials for thermal insulation have the shortage of larger pore size and insufficiently high mechanical properties, which are closely related to their fabrication methods. This paper is aimed to review the current research status of the preparation of porous ceramic materials for thermal insulation, analyze the problems in current research and outlook of the development trend.
Key words: porous ceramic; thermal insulation; preparation method; research progress; development trends
