Study on Preparation of Porous Light Refractory from Waste Electric Porcelain

In 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/cm 3 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. Graphical In this article, a new method of making porous thermal insulation refractory reusing waste electric porcelain was successfully developed. by this method, we prepared a sample with favorable bulk density of 0.81 g/cm 3 and apparent porosity of 61 %, and the room temperature flexural and compressive strengths are 11.52 Mpa and 1.84 Mpa.
