It is very important to study the low temperature sintering technology of alumina ceramics, whether for reducing energy consumption, saving cost, or improving performance.

The ceramic materials used for manufacturing textile components are required to possess high hardness, high strength, and excellent corrosion resistance. Commonly used ceramic materials for textile component fabrication can be categorized into four main types: alumina ceramics, titania ceramics, zirconia ceramics, and zirconia-toughened alumina ceramics.

During the preparation of DPC ceramic substrates, uneven distribution of electroplating current leads to non-uniform thickness of the copper layer on the substrate surface (thickness difference can exceed 100μm). Surface grinding is a key process to control the thickness of the electroplated copper layer and improve its uniformity, directly affecting the performance of ceramic substrates and the quality of device packaging.

Stable zirconia doped with yttrium has good comprehensive properties and is the most widely used solid electrolyte at present. Stable zirconia doped with magnesium oxide has general conductivity and low price, but its long-term performance is poor and is generally used as consumables.

Pyrolytic boron nitride is a new type of ceramic material prepared by chemical vapor deposition (CVD), while hot-pressed boron nitride is prepared by high temperature sintering processes such as pressureless sintering, hot pressing sintering and hot isostatic pressing sintering.

Currently, silicon nitride ceramics used in various fields are primarily prepared through reaction sintering, hot pressing sintering, pressureless sintering, gas pressure sintering, and hot isostatic pressing sintering. Different sintering processes yield silicon nitride ceramics with certain differences in performance, typically applied in different high-temperature structural components, wear-resistant components, or corrosion-resistant components.
