Andalusite Bricks

Andalusite bricks have a low impurity content and exhibit a very small decrease in high-temperature strength. They feature excellent resistance to rapid cooling and heating, high mechanical strength, strong thermal shock resistance, strong slag resistance, and high refractoriness under load.

Sillimanite Bricks

Sillimanite bricks feature a low thermal expansion rate, excellent resistance to corrosion from metallurgical slag and various molten glasses, and good high-temperature wear resistance. They have good high-temperature thermal stability, minimal pollution to molten glass, and high refractoriness under load.

Acid-Resistant Bricks

Acid-resistant bricks possess excellent corrosion resistance to organic and inorganic acids (excluding hydrofluoric acid), along with good strength and wear resistance. They are widely used in acidic atmosphere flues, autoclaves and recovery boilers in the acid pulping industry, as well as large acid-resistant pool containers and storage tanks.
