Sintered zirconia corundum bricks It is a high-performance refractory brick made of zirconium corundum (zirconia aluminum ore) after sintering. This brick combines the excellent properties of
zirconia and corundum, and has extremely high fire resistance and chemical corrosion resistance.
it have high strength and strong resistance to molten glass erosion. In addition, due to the presence of partially stable tetragonal ZrO2, microcracks are formed in the bricks. With a small amount
of porosity, its thermal shock resistance is superior to AZS fused cast bricks.

Features of Sintered zirconia corundum bricks :
High refractory: sintered zirconium corundum bricks can withstand extremely high temperatures, with a melting point usually between 1800°C and 2000°C
Excellent chemical corrosion resistance: It has strong corrosion resistance to many chemical media (such as molten metal, molten glass, acid and alkali).
High mechanical strength: The brick body maintains high strength at high temperatures and has excellent wear resistance.
Thermal stability: It can maintain stability in drastic temperature changes and reduce thermal shock damage to the material.
Application of Sintered zirconia corundum bricks :
Glass melting furnace: used in the high temperature area of glass melting furnace due to its excellent resistance to glass corrosion and high temperature resistance.
Electric arc furnace: used in electric arc furnaces for steel and other metals, withstanding the erosion of high temperature arcs and molten metals.
Petrochemical reactor: used for the lining of equipment in the process of handling high temperature chemical reactions, which can resist the corrosion of chemical media.
Ceramic kiln: used in high temperature ceramic kilns to maintain high temperature stability and reduce energy loss.
