摘要

Disclosed is an alumina porcelain composition, suitable for use after firing to form electric insulators, comprising from about 40 to 65% by weight of calcined alumina, from about 15 to 40% by weight of plastic kaolinite-montmorillonite constituents, and from about 20 to 26% by weight of a flux combination which contains alkali-aluminum silicates and from about 0.1 to 5% by weight of one or more alkaline earth oxides, preferably in the form of alkaline earth compounds. The flux combination preferably comprises about 22 to 24% by weight of potassium-aluminum silicates and from about 0.2 to 2.5% by weight of barium oxide in the form of barium compounds, thus avoiding the disadvantages associated with the use of TiO.sub.2 and MnO.sub.2.
