Alumina ceramics is one of the most researched and widely used materials among technical ceramics.

Alumina ceramic （al2o3 ceramic） is an industrial ceramic material with high hardness, high wear resistance and high mechanical strength. Its Rockwell hardness is HRA80-90, its hardness is second only to diamond, and its wear resistance far exceeds that of wear-resistant steel and stainless steel.

As a key component of semiconductor production equipment, the R&D and production of precision ceramic components directly affects the development of the semiconductor equipment manufacturing industry and even the entire semiconductor industry chain.

The sintering process has a crucial impact on the performance of the material. It is very important to choose a suitable sintering method when manufacturing different kinds of technical ceramics and for different property demands.

In practical applications, if the two materials can be jointed, they can make full use of their respective excellent properties to manufacture complex components that meet the requirements, reduce costs, and improve product performance and service life.

Ceramic locating pins are electrical insulating, have good wear resistance and mechanical strength, the wear resistance is in the top level among all existed materials. The superior wear resistance will reduce the looseness and poor alignment, ensure the precise welding.

The ceramic plungers are made of high-performance technical ceramic material, which has the properties of high hardness, wear resistance, high temperature resistance and corrosion resistance. The working surface of ceramic plungers are processed with a "mirror" surface and has good self-lubricating effect.

Industrial ceramics have excellent mechanical, thermal, and chemical properties such as superior strength, hardness, insulation, heat conduction, high temperature resistance, oxidation resistance, corrosion resistance, wear resistance, and high temperature strength, so industrial ceramics are used in very strict environmental engineering application conditions.

Dry pressing is based on a large pressure to press the powdery blank in the mold. The isostatic pressing molding method is also called hydrostatic molding, which is a molding method that utilizes the incompressibility of the liquid medium and the uniform transmission of pressure.

Electronic ceramics can be divided into five categories according to their functions and uses: insulating ceramics, capacitor ceramics, ferroelectric ceramics, semiconductor ceramics and ion ceramics.
