Alumina ceramic insulation has several important functions, mainly in the following aspects:
High - temperature resistance
• It can withstand high temperatures up to 1600℃ or even higher, maintaining stable physical and chemical properties, and is suitable for use in high - temperature environments such as furnaces and kilns.
Thermal insulation
• With low thermal conductivity, it can effectively reduce heat transfer, helping to save energy and maintain the temperature of the insulated object. For example, it is used in the insulation layer of industrial furnaces to reduce heat loss to the outside.
Electrical insulation
• It has excellent electrical insulation properties, which can prevent the leakage of electric current and ensure the safety and normal operation of electrical equipment. It is widely used in electronic components, high - voltage electrical insulation and other fields.
Mechanical properties
• Alumina ceramic insulation materials have high hardness and strength, which can resist certain mechanical impacts and abrasion, and have a long service life. They can maintain their integrity and insulation performance under harsh working conditions.
