High zirconia bricks composed of oblique zircon phase and a small amount of matrix glass phase, high zirconia brick has extremely high corrosion resistance, extremely low foaming rate and stone rate. As it hardly pollutes
molten glass, high zirconia fire bricks are mainly used for glass kiln walls, bottoms, liquid holes, electrode bricks and kiln ridges.
Features:
- High temperature stability: commonly used in high temperature furnaces, smelting furnaces and other places. It can maintain the stability of its physical and chemical properties in high temperature environments.
- Excellent corrosion resistance: It has very strong corrosion resistance to acidic and alkaline substances. This makes it perform well when handling some highly corrosive materials.
- Good thermal shock stability: It is not easy to crack even in an environment with rapid temperature changes. This is because its special crystal structure can effectively relieve thermal stress.
- High mechanical strength: It can withstand greater pressure and impact force and is suitable for use in high-temperature equipment with heavier loads.
- Low thermal conductivity: The thermal conductivity of high zirconium bricks is relatively low, which helps to reduce heat loss and improve the energy efficiency of furnaces.
- Chemical inertness: It is not easy to react chemically with other substances, which makes it stable in some complex chemical environments.

High zirconium bricks are widely used in various industrial fields that require high temperature and corrosion resistance due to their excellent high temperature stability, corrosion resistance, thermal shock stability and chemical inertness.
The high zirconia bricks main application areas:
- Metallurgical industry:
- Blast furnace: used for the lining of the blast furnace, which can withstand high temperature and erosion by molten iron.
- Electric arc furnace: used for the lining and inner lining of the electric arc furnace, which can withstand the extreme high temperature and chemical corrosion in the electric arc furnace.
- Converter: used to protect the lining in the converter to prevent corrosion of molten metal.
- Glass industry: Melting glass furnace: used for the lining of the glass melting furnace, which can withstand high temperature and erosion by molten glass.
- Ceramic industry: Firing furnace, used for the inner lining of the ceramic firing furnace, which can withstand high temperature and various chemical environments during the ceramic firing process.
- Chemical industry: used for corrosion resistance and heat insulation in some high temperature or highly corrosive chemical reactors.
- Petrochemical industry: used for the high temperature part of the catalytic cracking unit, which can withstand the corrosion of chemical media.
- Energy industry: used in the high temperature gas cooling system of the nuclear reactor to withstand high temperature and radiation environment.
- Aerospace: Used in rocket engine nozzles and combustion chambers, able to withstand extremely high temperatures and high impact forces.
