Alumina ceramics are the most common advanced ceramic materials and have been widely used in many industries, such as the electronic medical industry and the mechanical industry.
Alumina ceramics can be divided into several application grades according to their alumina purity, the more common are 95% alumina and 99% alumina, which have excellent physical properties.

Compared with metal sensor materials, ceramic sensor materials are mainly characterized by high elastic properties, small hysteresis, and good fatigue resistance, long-term stability and corrosion resistance at small displacement. Before the ceramic is broken, the stress-strain relationship is always linear, which is most suitable for the production of elastic components under high temperature work. At the same time, ceramic materials are cheap, so ceramic materials are highly valued in sensor materials.

Ceramic sensor materials can be divided into two categories: physical sensor materials for detecting energy and chemical sensor materials for identifying chemicals and their content. The former is sensitive to energy such as light, heat, pressure and sound, and can form sensors such as heat, position, speed and infrared. The latter accepts chemical substances and produces energy changes, which can constitute sensors such as gas sensors. There are many kinds of ceramic materials used for sensors, but most of them are oxide ceramics.
Application field:
① Low pressure and high vacuum: Ceramic sensors can measure differential pressures of less than 3.5mmHg compared to conventional sensors, and can withstand vacuum without causing damage or degradation to the product.
② Corrosive situations: The chemical corrosion resistance of the ceramic sensor makes the product composed of it can be used in almost any acidic situation.
