MATTONI O MASSE BASICI REFRATTARI A BASE DI MISCUGLI I OLIVINA MAGNESIA O A BASE DI SPINELLO DI MAGNESIO-ALLUMINIO, IN PARTICOLARE PER IL RIVESTIMENTO DI FORNI, E PROCEDIMENTO PER LA LORO PRODUZIONE

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.
