Abstract

Magnesite bricks are made from a mixture of sintered magnesite and from 10-30 per cent, referred to the weight of the brick, of chromium ore, and a substance, e.g. corundum, rich in alumina, the amount of the substance rich in alumina being about 4-7 per cent of the weight of the brick. The alumina is preferably in the form of fine meal, and the magnesite and chrome ore partly fine meal and partly coarse grains of 1-5 mm. In an example, a composition comprises 15 parts of magnesite, fine meal, 55 parts of magnesite coarse grains, 1-2,5 mm, 10 parts chrome, ore fine meal, 15 parts chrome ore coarse grains and 5 parts corundum.
