Abstract

1296329 Refractories NORTON CO 19 April 1971 [13 April 1970] 26311/71 Heading C1J A refractory mix comprises graded grains coated with 2-20% by volume of a vitrified glass. Specified grains are of Al 2 O 3 ; MgO; MgO.Al 2 O 3 ; ZrO 2 ; 2Al 2 O 3 .3MgO; optionals are clay, SiO 2 (which forms mullite with Al 2 O 3 grains), MgO (which forms spinel with Al 2 O 3 ). Not all the grains need be coated, and an organic plasticizer can be included.
