Alumina high-frequency ceramics have many practical properties and functions such as thermal stability and chemical stability, electrical insulation, piezoelectricity, corrosion resistance, chemical adsorption, biological adaptability, sound absorption and light transmission. . High-frequency ceramics, also known as device ceramics, are used in electronic equipment to install, fix, and protect components, as insulating supports for current-carrying conductors, and as ceramics for various integrated circuit substrates. It has small dielectric constant, low dielectric loss, high mechanical strength, and high dielectric strength, insulation resistance and thermal conductivity. With excellent electromechanical properties, it is the most widely used high-frequency insulating ceramic. It can be used to manufacture insulating parts of ultra-high frequency and high-power electric vacuum devices, and can also be used to manufacture ceramic shells of vacuum capacitors, ceramic components of microwave tube energy transmission windows, and various ceramic substrates.

Alumina high-frequency ceramics have the advantages of long life, energy saving, environmental protection, safety, and controllability. Due to its excellent electrical performance at high frequencies, it has low dielectric loss, high volume resistivity, high strength, high hardness, small linear expansion coefficient, and good wear resistance and heat resistance.

Alumina ceramic is a very hard ceramic that resists wear and is ideal for wear insert products. It is commonly used as a high-temperature electrical insulator, a high-purity alumina that provides better resistivity. It also has good resistance to acids and alkalis, even at high temperatures, which makes it excellent for resistance to corrosive substances. Some common applications include: electronic components and substrates, high temperature electrical insulators, high voltage insulators, laser tubes, machine components, mechanical seals, precision shafts and shafts in high wear environments, roller and ball bearings, sealing rings, semiconductor components, shooting Nozzles, thermocouple tubes, buckle discs, valve seats, wear components, wires and other fields.
