Application of Zirconia Ceramics in Refractory Materials:   1. High temperature materials: Zirconia has excellent fire resistance in high temperature environments and can withstand the erosion of high temperature environments and chemical corrosive substances. Therefore, zirconia is widely used in refractory materials such as kilns and crucibles in industries such as metallurgy, glass, and ceramics. 2. Corrosion resistant material: Zirconia has good corrosion resistance and can be applied in fields that require resistance to corrosive substances such as acid and alkali. For example, zirconia can be used to make anti-corrosion materials for use in high-temperature environments. 3. Coating material: Zirconia coating, as a high-performance protective coating, has good properties such as high temperature resistance, wear resistance, and corrosion resistance, and is widely used in high-temperature furnaces, high-temperature equipment, and other fields.   Application Cases: 1. Kiln lining: A large ceramic factory uses zirconia refractory material to make kiln lining, which has a service life of several years and reduces the cost and time of frequent lining replacement. 2. Crucible: A certain steel enterprise uses zirconia ceramics to make crucibles, successfully solving the problem of deformation and corrosion of traditional metal crucibles in high temperature environments, and improving production efficiency and product quality. 3. Special functional ceramics: A certain electronics company uses zirconia to prepare piezoelectric ceramics and successfully develops sensors with high sensitivity, low noise, and other characteristics, which are widely used in medical, environmental protection, and other fields.

Why can alumina ceramics be suitable for the medical field? This is closely related to the performance characteristics of alumina ceramics.   1. Wear resistance Alumina ceramics have excellent wear resistance and are suitable for making machine parts that can be used for a long time.   2. No deformation Alumina ceramic is an excellent material for developing precision parts, with excellent bending and compressive strength, and is not easily damaged.   3. Easy to clean Aluminum oxide ceramics have a smooth surface, are not easily adhered to impurities, and are easy to clean. So it is suitable for medical fields that require repeated use and hygiene maintenance.   4. Chemical resistant drugs Alumina ceramics have strong acid, alkali, and chemical corrosion resistance, so there is no need to worry about chemical reactions with other drugs during use.   5. Good insulation performance According to the purity of alumina, alumina ceramics can be divided into two types: high-purity and ordinary. High purity alumina ceramic is a very good insulation material due to its low impurities. As an insulating material, it is fully capable of withstanding voltage and has low volume efficiency. Even at high temperatures, it maintains insulation and has excellent heat resistance.   6. Plasma resistance As a high-purity alumina ceramic, it can be used as an anti plasma material due to its high purity and almost no intergranular segregation.
