BecauseAlumina ceramicIt has many distinctive properties, so it can be made into many different products. For example, because of its relatively high mechanical strength, it can be used as a mechanical structural part; and with its high resistivity, it is electrically insulating Due to its advantages such as good performance, alumina ceramics have become an ideal material for substrates, tube holders, circuit casings and other products.

In addition, the high hardness of alumina ceramics allows it to be used to make cutting tools, grinding wheels, abrasives, drawing dies, extrusion dies, bearings, etc. ; It also has the characteristics of high melting point and good corrosion resistance. It is also necessary as a material for furnace tubes, crucibles, fibers, thermocouple protection tubes, etc. In addition, alumina ceramics can also be made into pure metals and single crystals. Growing crucibles, human joints, artificial bones, sodium vapor lamps, microwave fairings, infrared windows, laser oscillation components, solar cell materials and battery materialsMaterials etc.

Alumina ceramics are also divided into different types. 99.7% alumina ceramics are made of high-purity alumina materials. The previous series of related strict process guarantees provide superior performance. Compared with 99% alumina and 95% alumina, it has higher density and higher bending strength.

99% alumina ceramic has the advantages of density and microstructure compared to 95% alumina, which is reflected in its suitable performance. The cost-effectiveness is suitable for parts with high performance requirements and moderate price. 95% alumina ceramics use pure alumina materials and diversified preparation processes to continuously reduce manufacturing costs while ensuring the intrinsic properties of alumina ceramics.

As a result, the performance indicators of 95% alumina ceramics have declined compared with the other two high-purity materials, resulting in The density is slightly lower, but it still has all the excellent properties of alumina ceramics. It is suitable for applying the characteristic advantages of alumina ceramics and is suitable for general parts.
