Introduction to the classification of semiconductor ceramics and its new characteristics

Introduction to the classification of semiconductor ceramics and its new characteristics

Due to its unique semiconductor characteristics, semiconductor ceramics are suitable for equipment with special requirements for materials, etc. The following Pintejin ceramic zirconia machining factory will introduce you to semiconductor ceramics.

Semiconductor ceramics refer to ceramic parts with semiconductor properties and electrical conductivity of about 10-6 to 105/m. The conductivity of semiconductor ceramics changes significantly due to changes in external conditions (temperature, light, electric field, atmosphere and temperature, etc.), so the physical quantity changes in the external environment can be converted into electrical signals to make sensitive components for various purposes.

Thermal ceramics: also known as thermistor ceramics, refers to ceramics whose conductivity changes significantly with temperature.

Thermal semiconductor ceramic tube

Thermal ceramics are mainly used for temperature compensation, temperature measurement, temperature control, fire detection, overheat protection and color TV degaussing, etc.

Photosensitive ZTA ceramics: refers to ceramics with photoconductive or photovoltaic effect. Such as cadmium sulfide, cadmium telluride, gallium arsenide, indium phosphide, bismuth germanate and other ceramics or single crystals.

The conductance increases when light hits its surface. Mainly used for automatic control of light switches and solar cells, etc. Semiconductor Porcelain Tube.

Gas Sensing CeramicsZirconium Oxide Processing Semiconductor Ceramics

Gas-sensitive ceramics: refers to ceramics whose conductivity varies with the type of gas molecules in contact. Ceramics of systems such as zinc oxide, tin oxide, iron oxide, vanadium pentoxide, zirconium oxide, nickel oxide and cobalt oxide.Mainly used for leak detection, disaster prevention alarm and measurement of different gases

Humidity-sensitive ceramics: refers to ceramics whose electrical conductivity changes significantly with humidity. Such as ferric oxide, titanium oxide, potassium oxide-iron oxide, magnesium chromate-titanium oxide and zinc oxide-lithium oxide-vanadium oxide and other systems. Their conductivity is particularly sensitive to water, making them suitable for humidity measurement and control.
