The Common Firing Techniques For Alumina Ceramics

The technical method of densifying a granular ceramic body and forming a solid material is called sintering. Sintering is a method of removing the voids between the particles in the body, removing a small amount of gas and impurity organic matter, and making the particles grow and combine with each other to form a new substance. Electric furnaces are widely used as heating devices for firing. In addition to normal pressure sintering, that is, pressureless sintering, there are also hot pressing sintering and hot isostatic pressing sintering. Although continuous hot pressing sintering increases the output, the cost of equipment and molds is too high. In addition, due to the axial Read more

The Classification And Application Of Silicon Nitride Ceramic Materials

Silicon Nitride (Si3N4) has the most versatile combination of mechanical, thermal and electrical properties of any technical ceramic material. It is a high-performance technical ceramic, very hard, with excellent thermal shock and impact resistance. It exceeds the high temperature capabilities of most metals and has excellent creep and oxidation resistance. Additionally, its low thermal conductivity and high wear resistance make it an excellent material to withstand the harshest conditions in the harshest industrial applications. Silicon nitride is an excellent choice when high temperature and high load capacity are required. Silicon Nitride is one of the hardest technologies available for ceramics and has been used successfully for many years in a Read more
