BASIC, FIRE-RESISTANT STONES OR MASSES BASED ON OLIVINE-MAGNESIA BLENDS OR MAGNESIUM-ALUMINUM SPINEL WITH A CONTENT OF CELSIAN

摘要

A basic refractory brick or composition based on a mixture of olivine and magnesia, or on magnesium aluminium spine, contains celsian (or components capable of forming celsian) when fired in an amount of 1 to 20 weight-%, calculated as barium oxide. The composition may be used for lining a rotary tubular cement furnace or the regenerator of a glass tank furnace.
