Zirconia Bricks Manufacturers

Zirconia bricks are advanced refractory materials that find a wide range of applications in industries where high temperature and harsh chemical environments are present. These bricks are primarily composed of zirconium dioxide (ZrO2), a ceramic material known for its exceptional thermal and chemical resistance.

Due to their unique properties, zirconia bricks are used in various critical industrial processes.In the steel and iron industries, zirconia bricks are utilized to line ladles, tundishes, and other equipment used in the casting and refining of metals.

Raw material preparation: The raw materials for zirconia bricks are zircon sand, alumina, and a binder. The zircon sand must be high purity and free of impurities such as iron and titanium. The alumina is used to improve the strength and thermal shock resistance of the bricks. The binder is used to hold the particles together during the sintering process.
Mixing: The raw materials are mixed together in a ball mill or other mixing machine. The mixing is done to ensure that the particles are evenly distributed and that the binder is uniformly dispersed.
Forming: The mixed powder is then formed into the desired shape of the brick. This can be done by isostatic pressing, dry pressing, or slip casting.
Sintering: The formed bricks are then sintered in a furnace. The sintering process is a heat treatment process that causes the particles to fuse together. The sintering temperature and time are critical to the properties of the final product.

These Bricks Can Provide Great Insulation From Heat

Zirconia bricks are made from zirconium oxide, a material with a very high melting point and low thermal conductivity. This means that zirconia bricks can withstand very high temperatures without melting or decomposing, and they are very effective at slowing down the transfer of heat.

Zirconia bricks are also very strong and resistant to corrosion, making them ideal for use in high-temperature applications where heat insulation is critical. For example, zirconia bricks are often used in furnaces, kilns, and incinerators to help prevent heat loss and protect the surrounding materials from damage.

The process of producing aluminum involves several key steps, culminating in the extraction of approximately 80% pure aluminum. It begins with bauxite mining, where bauxite ore, a mineral-rich rock containing aluminum oxide, is extractedIf you are looking for a high-performance heat insulation material, zirconia bricks are a great option.
