Physical properties of al2o3 ceramic plate：
Al2o3 ceramic plate has excellent physical properties, such as high hardness, high melting point, and high coefficient of thermal expansion. It is second only to diamond and sapphire in hardness and is one of the hardest of all common ceramic materials. It has a melting point of about 2072°C and is able to maintain stability at high temperatures. In addition, alumina ceramics have a low coefficient of thermal expansion, which is similar to that of metals, so they are not easily deformed at high temperatures.
Good chemical stability：
Alumina ceramics have good chemical stability at room temperature. It has high stability to acids and alkalis and is not easily corroded. Therefore, alumina ceramics are often used in some chemical laboratories and industrial production, such as reagent bottles and acid-base containers. In addition, alumina ceramics are also resistant to wear and corrosion, and can maintain good performance in the environment of friction and wear.
Insulation Properties:
Alumina ceramics are an excellent insulating material. It has excellent electrical insulation properties, can remain stable at high temperatures and high pressures, and is not easy to conduct electricity. Therefore, alumina ceramics are often used as insulating substrates for electronic devices, wire insulating sleeves, etc.
Advantages and applicaton of al2o3 ceramic plate:
Alumina ceramics have the advantages of stable material structure, high mechanical strength, high hardness, high melting point, corrosion resistance, excellent chemical stability, high resistivity, good electrical insulation performance, they are widely used in semiconductor equipment.
