Silicon Nitride Ceramic Protection Tube for Molten Aluminum
Silicon Nitride Substrate Materials Description: Silicon Nitride (Si3N4) has good high temperature strength, creep resistance and oxidation resistance.In addition, its low thermal expansion coefficient gives excellent thermal shock resistance compared with most ceramic materials. The fact that this ceramic material is an extremely low-friction and non-magnetic material with a very low specific weight, excellent dry running properties and therefore superior emergency operating features is what makes it the material of choice for demanding applications,like ceramic bearing.
