How To Make Thermally Conductive Ceramics Better?
The properties of the material itself, in fact, determine its application to a large extent. Like most ceramic materials, the heat transfer performance is worse than that of metal materials, so the application in the field of heat conduction is not as much as that of metal materials. But even so, because ceramic materials have high melting point, high hardness, high wear resistance, oxidation resi...

Application of Gas Pressure Sintering Method in the Production of Silicon Nitride Ceramic Products
Gas pressure sintering: At present, large-size and complex-shaped ceramic products mainly rely on air pressure sintering technology. During the gas pressure sintering process, the applied gas pressure mainly suppresses the thermal decomposition of silicon or other nitride-based high-temperature materials. Because silicon nitride begins to decompose under normal pressure above 1750 degree...

Changes of Alumina Ceramic Structure Under High Temperature
1. Creep The structural parts of alumina ceramics will be subjected to external forces at high temperatures, and with time, plastic changes will continuously and slowly happen . This phenomenon can be called creep. When the structural parts of alumina ceramics creep, there is a great relationship between the stress and the temperature. In addition, when the stress increases or the temper...

Thermal Management Materials for Electronic Components-thermally Conductive Ceramic Substrate
Thermally conductive ceramic substrate is a material with high thermal conductivity. It is mainly made of alumina (alumina purity up to 96% or more). It has a pure white appearance and a hard texture. It is mainly used for heat transfer between power devices and radiators and electrical isolation. After it is tightly combined with power devices (such as power MOS tubes, power transistors...

Manufacturing Process of Alumina Ceramics
Alumina ceramics is a ceramic product composed of α-Al2O3 as the main crystal, and its Al2O3 content is generally above 75%. People usually classify them according to the content of Al2O3 in the ingredients. Among them: the content of Al2O3 is about 75% is "75 alumina". Because the sintering temperature of Al2O3 is lower, the cost of 75 alumina is lower than other alumina ceramics, but becaus...
