  ★Electrical insulating ceramics.

  Electrical insulating ceramics are widely used in metal solution baths,molten salt containers,packaging materials,and integrated circuits due to their good thermal conductivity,low electrical conductivity,low dielectric constant,low dielectric loss,high mechanical strength and good chemical stability Substrate,electrolytic cell lining,metal matrix composite reinforcement materials,active armor materials,radiators and heating parts of high-temperature furnaces.

  In the electronics and power industry,insulating ceramics such as insulators,insulating sleeves,resistance seats,coil formers,tube seats of electronic tubes and power tubes,and integrated circuit substrates of power equipment are mainly used for the installation,protection,support,insulation,and insulation of electrical equipment.Connect and isolate.

  ★Dielectric ceramics.

  At present,dielectric ceramics are widely used as integrated circuit substrate materials due to their high strength,low dielectric loss,heat resistance and stability.For example,beryllium oxide,aluminum oxide,aluminum nitride,and silicon carbide can be widely used as ceramic materials for integrated circuit substrates.

  ★Piezoelectric ceramics.

  When piezoelectric ceramics are used as sensitive materials,piezoelectric seismometers can monitor subtle vibrations that humans cannot perceive,thereby effectively predicting earthquakes and reducing losses;piezoelectric actuators made of piezoelectric effects are used in microelectronics,precision machinery and biological engineering Important device.Piezoelectric ceramics are used in ultrasonic transmitters,and can be used for ocean exploration,underwater navigation,ultrasonic cleaning,medical imaging,solid detection,ultrasonic disease treatment,etc.In addition,piezoelectric ceramics are also widely used in precision instruments,aerospace,office automation,micromechanical systems,precision positioning and other fields.
