Low Alumina Bricks

JBTC offers exclusive range of LOW ALUMINA bricks with various qualities we guarantee our bricks to be of superior quality.

The term Low Alumina refers to the bricks having AL203 content lower than 47.50%.

They are designed primarily for ladles. These 50% lower alumina class brick have low porosity and expand upon reheating to 2910°F (1600°C) - desirable features for ladle applications since they minimize joints between brick, giving a near monolithic lining at service temperature.

These brick are also characterized by low thermal expansion and good resistance to spalling. Many high-temperature industries use them as backup brick,alumina products based on high purity bauxitic kaolin, and other ingredients in the matrix, provide exceptional load-bearing ability, alkali resistance and low porosity. These qualities make such brick an excellent choice for preheater towers and calcining zones of rotary kilns.
