Different purposes of sintering alumina ceramics
Alumina ceramics actually uses alumina as the main material, a ceramic product produced by the manufacturer or produced, and is mainly used in thick film integrated circuits. Moreover, alumina is very good in conductivity, high temperature resistance and mechanical strength, but when using alumina ceramics, the most important thing to pay attention to is the ultrasonic cleaning.
Moreover, alumina ceramics are also very common in the scope of use. Because alumina ceramics are very superior in performance, they are widely used in many different industries, which can meet the daily use needs and some The performance requirements of the script are relatively special, and the use of alumina ceramics in the industry is very significant.
In the manufacture of alumina ceramics, the main purpose is to sinter the granular ceramic green body in a dense manner. The main purpose of sintering is to eliminate the gap between the green body and the particles and remove a small amount of it. The gas and the magazine are evacuated to ensure that the particles can be combined for a longer time and form a processing method for different materials.
Although the continuous hot pressing sintering method can effectively increase the output of alumina ceramics, the processing equipment used and the related manufacturing costs are relatively high, and the axial heating is not particularly uniform, so The length of alumina ceramic products will be affected by the above-mentioned problems.
Because alumina ceramics are relatively good in structural uniformity, the performance of the material is the same as that of cold-pressed sintering, and the performance can be improved by 30% to 50%, which is better than ordinary alumina ceramic products. There are many. At present, this kind of alumina ceramic products are used in many special parts. The more common ones are reflectors and ceramic bearings.
