Abstract

1281154 Refractories HEINRICH KOPPERS GmbH 23 July 1970 [1 Aug 1969] 35681/70 Heading C1J A mixture of MgO.Al 2 O 3 (spinel) with up to 60% ZrO 2 is shaped and fired to form a MgOAl 2 O 3 -ZrO 2 system refractory. Up to 20% of MgO or Al 2 O 3 can also be included. Firing is in a normal, N 2 or H 2 atmosphere.
