Silica Bricks

Silica bricks have high high-temperature strength, a high refractoriness under load (1620 ~ 1680℃), and strong resistance to acidic slag corrosion. They do not deform after long-term use at high temperatures. The residual expansion during heating makes the masonry joints tight, ensuring good gas tightness and structural strength of the masonry. They are mainly used in thermal kilns such as coke ovens and glass melting furnaces.

Magnesia Zirconia Bricks

Magnesia zirconia bricks feature a dense structure, small and evenly distributed pores, high high-temperature strength, good thermal shock resistance, and good resistance to alkaline corrosive atmospheres and alkaline slag. They also have excellent kiln coating performance. They are suitable for the burning zone of cement kilns and the regenerators of glass melting furnaces.

High Zirconia Bricks (Fused Cast High Zirconia Bricks)

High zirconia bricks are composed of the baddeleyite phase and a small amount of matrix glass phase. They feature extremely high corrosion resistance, extremely low blistering and stone-forming rates, and almost no pollution to molten glass. They are mainly used in areas such as the side walls, bottoms, doghouses, electrode blocks, and thresholds of glass melting furnaces.

Alkali-Resistant Bricks

Alkali-resistant bricks are characterized by high strength, good volume stability, and excellent resistance to alkali corrosion. During use, they react with alkali to form a high-viscosity glass phase that prevents the penetration of alkaline slag, demonstrating good corrosion resistance against metallurgical slag, cement clinker, and other materials.

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.
