Zirconia ceramics have various functions in electronic devices, mainly reflected in the following aspects:

Capacitor material: Zirconia ceramics are often used as capacitor materials in electronic devices. Due to its high dielectric constant and stable dielectric performance, zirconia ceramics can provide high electrical capacity and stable electrical performance for manufacturing high-performance capacitors.

Piezoelectric devices: Zirconia ceramics have a piezoelectric effect, which is the characteristic of generating mechanical displacement under the action of an external electric field or changing charge distribution when subjected to mechanical pressure. Therefore, zirconia ceramics can be used to manufacture piezoelectric ceramic sensors, piezoelectric transducers, and other piezoelectric components.

Ceramic substrate: Zirconia ceramics are often used as substrate materials for electronic devices due to their high temperature stability and insulation performance. In integrated circuit manufacturing, zirconia ceramic substrates can provide good mechanical support and electrical insulation, while also having high thermal conductivity.

Ceramic packaging materials: Zirconia ceramics are often used as packaging materials for electronic devices due to their excellent high temperature resistance and chemical stability. It can effectively prevent electronic devices from being damaged by the external environment, improve the reliability and durability of the devices.

Dielectric materials: Zirconia ceramics have good insulation properties and dielectric properties, and can be used as dielectric materials in electronic devices, such as dielectric substrates in microwave devices, high-frequency capacitors, etc.
