Zusammenfassung:The invention discloses an electrical porcelain added with aluminum manufacturer sludge and a preparation method thereof. Raw materials for the electrical porcelain added with the aluminum manufacturer sludge include, by weight, SiO2 10-20%, Al2O3 10-25%, Fe2O3 10-20%, TiO2 1-5%, CaO 2-10%, MgO 0-3%, K2O 5-15%, Na2O 3-8% and the aluminum manufacturer sludge 2-15%. The added aluminum manufacturer sludge can promote crystallization process of a mullite phase in the electrical porcelain, and the breakage strength of the electrical porcelain is remarkably improved; waste reutilization is achieved, and the electrical porcelain has important economic and social benefit. The electrical porcelain is simple in raw material preparation, easy to obtain and stable and mature in process and meets the practical and industrial conditions.
