Zirconia mullite bricks have the strength and toughness of zirconia and the thermal shock resistance and stability of mullite.Fireramo offers high quality zirconia mullite bricks for sale and wholesale.
Zirconia Mullite Brick is a firebrick used in high temperature industrial applications where resistance to thermal shock, corrosion and abrasion is required. It is produced by mixing zirconia (ZrO2) and mullite with a binder and then firing at high temperatures. The material has a unique microstructure that combines the strength and toughness of zirconia with the thermal shock resistance and stability of mullite.Fireramo supports customized zirconia mullite bricks in a variety of shapes and sizes.
High Temperature Resistance
Zirconia mullite bricks can withstand temperatures up to 3272°F (1800°C), making them ideal for high-temperature industrial processes.
Excellent thermal shock resistance
Zirconia mullite bricks can withstand rapid temperature changes without cracking or fracturing, making them ideal for applications with frequent temperature fluctuations.
High strength and toughness
Zirconia mullite bricks have a unique microstructure, with the strength and toughness of zirconia and the thermal shock resistance and stability of mullite, so they are highly resistant to wear and abrasion.
Good chemical stability
Zirconia mullite bricks are resistant to most chemicals and can withstand the erosion of corrosive materials, so they are suitable for use in harsh industrial environments.
Low thermal conductivity
Zirconia mullite bricks have a low thermal conductivity, which means that they effectively insulate against heat transfer, keeping the heat inside the furnace or kiln.
Low porosity
The low porosity of zirconia mullite bricks reduces the penetration of molten material into the brick, making it resistant to thermal shock and corrosion.
High erosion resistance
Zirconia mullite bricks have excellent erosion resistance and are suitable for applications with high mechanical wear.
Steelmaking
Zirconia mullite bricks are often used as linings for ladles and other high-temperature steelmaking equipment because of their excellent resistance to thermal shock, abrasion and corrosion.
Glassmaking
Zirconia mullite bricks are used in the construction of glass kilns because of their excellent resistance to thermal shock and the reduced risk of glass contamination.
Petrochemical refining
Zirconia mullite bricks are used in reactors and furnaces in petrochemical refining processes, where zirconia mullite bricks are exposed to high temperatures and corrosive substances.
Incineration
Zirconia mullite bricks are used in waste treatment incinerators, where they are exposed to high temperatures and corrosive substances.
Power generation
Zirconia mullite bricks are used in combustion chambers and boilers in power plants, as well as in gasifiers for the production of synthetic fuels.
Ceramics
Zirconia mullite bricks are used in the production of high-grade ceramics with excellent thermal shock and wear resistance.
Aerospace industry
Zirconia mullite bricks have excellent thermal insulation and high temperature resistance, and can also be used to produce insulation panels for spacecraft and other aerospace applications.
Zirconia mullite bricks are an advanced refractory material that can be used in a wide range of applications where other refractories may not be suitable.
