insulated cooling 99% alumina ceramic shell case sleeve

insulated cooling 99% alumina ceramic shell case sleeve Reputation depends on quality,  quality comes from Hard! Alumina Ceramics: Preparation process: due to different preparation processes, various types of silicon nitride ceramics have different microstructures (such as porosity and pore morphology, grain morphology, intergranular morphology, and intercrystalline second phase content, etc.) and therefore various properties There is a big difference. To obtain Si3N4 ceramic materials with excellent performance, first of all, high-quality Si3N4 powders should be prepared. The quality of Si3N4 powders prepared by different methods is not completely the same, which leads to the difference in their uses. , Often attributed to the developers do not understand the differences between various ceramic powders, and their lack of understanding of their properties. In general, high-quality Si3N4 powder should have a high alpha phase content, uniform compositi…
