High Requirements for Refractory Materials in the Ceramic Industry

The ceramic industry demands high - quality refractory materials due to the extreme conditions in ceramic kilns. Temperatures in ceramic kilns can reach up to 1500°C, and these materials are also exposed to chemical corrosion and mechanical wear. Traditional refractory materials, such as clay - based bricks, have certain limitations. For example, their refractory degree may only reach about 1300°C, and they have relatively poor wear - resistance and corrosion - resistance, which often leads to frequent replacement and increased production costs.

Physical and Chemical Characteristics of Corundum Bricks

Corundum bricks are made of high - purity corundum raw materials, endowing them with excellent physical and chemical properties:

• High Wear - Resistance: Corundum bricks have a hardness of about 9 on the Mohs scale, which is second only to diamond. This high hardness makes them highly resistant to mechanical wear caused by the movement of ceramic products or the flow of hot gases in the kiln.
• Corrosion - Resistance: They can resist the corrosion of various acidic and alkaline substances. In ceramic production, many glazes and fluxes contain acidic or alkaline components. Corundum bricks can maintain their integrity and performance in such environments, with a corrosion rate of less than 5% under long - term exposure.
• High Refractory Degree: The refractory degree of corundum bricks can reach over 1800°C, which can fully meet the high - temperature requirements of different ceramic firing processes.
• Chemical Stability: Corundum bricks have excellent chemical stability and do not react easily with other substances in the kiln, ensuring the purity of the ceramic firing environment.

Actual Application Effects of Corundum Bricks in Different Ceramic Production Scenarios

In large - scale porcelain production, corundum bricks are used in the key parts of the kiln, such as the burner area and the product support area. For example, a well - known ceramic factory in Italy replaced its traditional refractory bricks with corundum bricks in the burner area. As a result, the service life of the kiln lining in this area increased from 1 year to 3 years, and the energy consumption was reduced by about 15% due to better heat insulation performance.

In the production of fine - art ceramics, corundum bricks are used to create a stable and clean firing environment. A Japanese ceramic studio found that after using corundum bricks, the defect rate of their high - end porcelain products decreased from 10% to 3%, significantly improving product quality.
