Because alumina ceramics have many unique properties, they 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 advantages such as high resistivity and good electrical insulation performance, alumina ceramics have become an ideal material for substrates, tube holders, circuit shells and other products.
In addition, the high hardness of alumina ceramics allows it to be used to make knives, grinding wheels, abrasives, wire drawing dies, extrusion dies, bearings, etc.; it also has the characteristics of high melting point and good corrosion resistance, and is also a must-have material for furnace tubes, crucibles, fibers, thermocouple protection tubes, etc.; in addition, alumina ceramics can also be made into pure metal and single crystal growth crucibles, human joints, artificial bones, sodium vapor lamps, microwave fairings, infrared windows, laser oscillator components, solar cell materials and battery materials.
Alumina ceramics are also divided into different types, of which 99.7% of alumina ceramics are made of high-purity alumina materials, and with a series of related strict process guarantees, the performance is even better. Compared with 99% alumina and 95% alumina, it has higher density and bending strength.
Compared with 95% alumina, 99% alumina ceramics have advantages in density and microstructure, which is reflected in the performance with suitable cost performance, and is suitable for parts with high performance requirements and moderate prices. 95% alumina ceramics use pure alumina materials and diversified preparation processes, while ensuring the intrinsic properties of alumina ceramics, while continuously reducing manufacturing costs.
As a result, compared with the other two high-purity materials, the performance indicators of 95% alumina ceramics have declined, and the density is slightly lower, but it still has all the excellent properties of alumina ceramics, which is suitable for the characteristic advantages of alumina ceramics and is suitable for general parts.
