Silica Bricks for Glass Furnace Crowns
High-quality silica refractories for glass melting furnace crowns and superstructure
Silica Bricks for the Glass Industry
Silica brick is the preferred refractory material for glass melting furnace crowns worldwide. It offers excellent volume stability at high temperatures and good resistance to alkali vapors, making it the optimal choice for this critical application.
Alzar FZE supplies silica bricks in multiple grades to meet the requirements of different types of glass furnaces. We work with glass manufacturers across the UAE and GCC countries to select the appropriate grade and provide technical support.
Silica Brick Properties
High Temperature Resistance
Silica bricks withstand temperatures up to 1,700°C, making them suitable for glass furnace crowns and superstructure areas where temperatures are elevated.
Volume Stability
Silica bricks exhibit excellent volume stability at high temperatures after initial expansion. This makes them ideal for furnace crowns where dimensional stability is critical.
Alkali Vapor Resistance
Different grades are available with varying alkali vapor resistance, allowing selection of the appropriate grade based on the glass composition being produced and operating conditions.
Long Service Life
When the correct grade is selected and properly installed, silica bricks provide long service life in glass furnace crowns, reducing repair frequency and downtime.
