Alumina ceramic ring is a mechanical accessory processed from alumina ceramic. Because of its superior performance, its application in modern society has become more and more widespread. What are the advantages of alumina ceramic ring and how is it processed? ? Chemshun Ceramics manufacturer will tell you.
ceramic ring is an accessory made of ceramic material based on alumina (al2o3). It has the following main advantages:
1. Excellent insulation, relatively small high-frequency loss but good high-frequency insulation.
2. Heat resistance, small thermal expansion coefficient, high mechanical strength and good thermal conductivity.
3. Chemical corrosion resistance and molten metal resistance.
4. The alumina ceramic ring is non-combustible, stainless, strong and not easily damaged. It has excellent properties that are incomparable to other materials and metal materials.
5. Alumina ceramics have wear resistance, but the hardness is the same as corundum. To reach Mohs hardness level nine, the wear resistance must be comparable to super-hard alloys.
Processing of alumina ceramic rings:
1. Due to the high hardness of alumina ceramic materials, harder grinding and polishing brick materials need to be used for finishing, such as silicon carbide, boron carbide, diamond, etc., usually grinding step by step from coarse to fine abrasives, and then the surface polishing.
2. Some alumina ceramic materials still need to be finished after sintering. For example, products that can be used as artificial bone require a high surface finish, like a mirror surface, to increase lubricity.
3. Alumina ceramic rings can generally be ground and polished with Al203 micron powder or diamond paste <1 μm. In addition, laser processing and ultrasonic processing grinding and polishing methods can also be used.
In addition to ceramic rings, Chemshun Ceramics also provides wear-resistant ceramic straight tubes, tapered tubes, curved tubes, etc. Welcome to consult.
