Super Duty Silica Bricks
Firebird glass furnace super duty silica bricks are made from plant owned high purity silica mineral, sintered in gas fueled down draft kiln.
The bricks enjoy the characters of high purity (high SiO2 content, low Fe2O3 content, Low flux factors), high refractoriness under load, high tridymite content, high density & high strength, low true density, low expansion & low creep rate, accurate size tolerance.
Typical Application
Crown and superstructure of glass melting tank and regenerators.
