Process for producing a porcelain, porcelain and ceramic insulator made from a porcelain The invention describes a process for producing a porcelain, an in particular high-strength porcelain and a ceramic insulator. To produce the porcelain, calcined bauxite (B) is used instead of alumina. The simultaneous addition of clay (T) and kaolin (K), in each case containing more than 5% by weight of foreign metal oxide inclusions, results in a porcelain which, compared to an alumina porcelain of the same mechanical strength, can be produced at significantly lower cost. The porcelain is suitable in particular for applications for highly mechanically loaded components used in electrical insulation. |
