Patent DE-4122023-A1 (DE)
Inventor: LIEBERMANN JOHANNES DIPL ING
IPC: C04B33/26
Filed: 1991-07-03
Abstract: Alumina porcelains, such as are used especially in electrical insulators, involve the problem of the high-strength alumina porcelains containing a higher proportion of calcined alumina and consequently having a higher sintering temperature. The normal-strength alumina porcelain compositions are therefore not compatible with the high-strength porcelain compositions, so that a fluid transition in production from normal-strength to high-strength alumina porcelains was not possible. In this connection, the invention provides that, at a specific bending strength of more than 190 DEG N/mm<2> on a glazed bending rod, only 33 to 45% by weight of calcined alumina and, as sintering aid, one or more of the substances magnesium oxide, calcium oxide and/or zinc oxide are present, the quantities of magnesium oxide and calcium oxide being each less than 1.5% by weight, and the quantities of zinc oxide being less than 0.8% by weight. The invention is applicable to industrial porcelain, in particular for electrical insulators.
