Aluminum Oxide Bricks, including low creep bricks, are typically used in industry furnaces such as blast furnaces. Aluminum Oxide Bricks have a temperature of refractoriness under load of above 1420~1550, which increases as the Al2O3 content enhances. Aluminum Oxide Bricks have a high anti-acidity, anti-oxidation and anti-metal fluid corrode but have less thermal shock resistance than the fireclay brick. High Alumina Bricks are generally immediately available in most volumes.
-Ethylene pyrolysis furnaces
