Abstract
AbstractIn the process of the development of the ceramic industry, a large amount of ceramic solid waste is generated, and how to make high‐value reuse of ceramic solid waste has also become a problem of common concern. In this article, a new method of making porous thermal insulation materials reusing waste electric porcelain was successfully developed. In this work, a porous light refractory with bulk density of 0.99 g/cm3 and apparent porosity of 59% was prepared by the novel method. Which room temperature flexural and compressive strengths are 11.52 MPa and 1.84 MPa, respectively. These properties makes the waste electric porcelain‐based porous light refractory can be applicated as lightweight heat insulation materials for high‐temperature kilns, high‐temperature catalyst carriers, high‐temperature phase‐change heat storage support materials, etc., which will create higher application value and research significance.
