The big defect of alumina ceramics should be the product blackening, but this will not affect its normal use, we should find out the blackening factors at a fast speed, and targeted to its related solutions, to ensure that its performance will not change, what specific ways to improve?
When we choose ceramic glaze in alumina ceramics, the choice of raw materials is very important, the best use is not easy to smoke raw materials, because this material can reduce the atmosphere in the degree of sensitivity, but also need to be effective control of the ceramic glaze on the temperature.
Want to ensure that alumina ceramics can reach the state of brightness, the best glaze firing temperature, and metal temperature control in 10℃, so that the maximum extent of the glaze appears black phenomenon to reduce, but also can be used to alumina ceramics in the performance of the effective promotion, so this way is more effective.
Moreover, after the improvement of the black rough surface of alumina ceramics, can also be appropriate to improve the atmosphere of the equipment, the most important is to inhibit black alumina ceramics appear black, has a more obvious role and effect, mentioned above to reduce the appearance of black, we should still pay attention to.
If you want to make alumina ceramics into powder, it is actually a very difficult thing, although professionals have tried many different ways and methods, but the effect is not very obvious, and finally did not get a more ideal powder products, what is the problem?
In the traditional way of making powder of alumina ceramics, it is easy to agglomerate in the process of calcination, so powder cannot be obtained at one time. Moreover, particles will increase continuously due to the temperature of calcination, which is also the most troublesome problem for the production staff, but there is no substantial solution.
Alumina ceramic grinding of, also will be affected by the secondary pollution, that is why cannot produce high performance powder, the main factors can even get powder, also can not directly to make it into the ceramic pieces, because can't meet the requirements on the density of sintered, can lead to products on the performance is affected by the serious.
