Use And Further Development Of Magnesia-Zircon Bricks In The Glass Industry

The first refractory material on a base of 80% magnesia and 20% zirconium silicate was introduced in 1986. The intention was to solve problems in the condensation zone of checkers. This paper presents practical results of more than 20 installations. Based on the good experience of these installations, a further magnesia-zircon brand was developed to solve the problems in the upper checkers, regenerator walls, and crowns, as well as in crowns of melting chambers of soda-lime and insulation wool furnaces.
