Because alumina ceramics have many different properties, it can be made into many different products. For example, because of its high mechanical strength, it can be used as mechanical structure parts. With the advantages of high resistivity and good electrical insulation performance, alumina ceramics can be used as the ideal production material for substrate, socket, circuit shell and other products.
In addition, due to its high hardness, alumina ceramics can be used to make cutting tools, grinding wheels, abrasives, wire drawing dies, extrusion dies, bearings, etc.; it also has the characteristics of high melting point and good corrosion resistance, which are necessary for making furnace tubes, crucibles, fibers, thermocouple protection tubes, etc.; in addition, alumina ceramics can also be used to make crucibles, human joints, artificial bones of pure metal and single crystal growth Sodium vapor lamp, microwave fairing, infrared window, laser oscillation components, solar cell materials and battery materials, etc.
Alumina ceramics are also divided into different types, of which 99.7% alumina ceramics are made of high-purity alumina materials, with a series of strict process guarantee, the performance is more superior. Compared with 99% alumina and 95% alumina, it has higher density and higher bending strength.
Compared with 95% alumina, 99% alumina ceramic has the advantages of density and microstructure, which is reflected in the appropriate performance price ratio, suitable for parts with high performance requirements and moderate price. 95% alumina ceramics adopt pure alumina materials and various preparation processes, which can ensure the intrinsic characteristics of alumina ceramics and continuously reduce the manufacturing cost.
As a result, compared with the other two kinds of high-purity materials, 95% alumina ceramic has lower performance index and lower density, but it still has all the excellent properties of alumina ceramic, which is suitable for the characteristic advantages of alumina ceramic and general parts.
