Zirconia has wide applications in the refractory materials industry, mainly in the following aspects:
High-temperature refractory materials: Due to its excellent high-temperature performance and chemical stability, zirconia is often used as an additive in high-temperature refractory materials. Adding zirconia to refractory materials can improve their heat resistance, corrosion resistance, and wear resistance, extending the service life of the materials. Zirconia is commonly used in the preparation of refractory materials for high-temperature kilns, glass kilns, etc.
Refractory coatings and adhesives: As a common component of refractory materials, zirconia can also be used in the preparation of refractory coatings and adhesives. After mixing zirconia with binders and other components, refractory coatings and adhesives with good high-temperature performance can be formed, used to protect and repair the surfaces of high-temperature equipment.
Ceramic industry: Due to its high strength, wear resistance, and thermal expansion properties, zirconia is widely used in the ceramic industry. Zirconia is often used to prepare high-performance ceramic products, such as cutting tools, tiles, and ceramic catalysts.
High-temperature melt temperature measurement: Zirconia has good electrical conductivity at high temperatures, so it is used as a sensor material for high-temperature melt temperature measurement. By making zirconia into thermocouples or thermistors, the temperature of high-temperature melts can be measured.
