The raw materials we use to make specialty ceramics are relatively scarce, especially high-end raw materials. Special ceramic raw materials, unlike ordinary ceramics, can be collected in the surrounding areas, special ceramics for raw materials purity and sintering activity requirements, otherwise it will affect the stability of product quality.

Compared with the advanced foreign technology, the technology of making special ceramics in our country still has a long way to go, especially in practical application, production level and degree of industrialization.
The raw materials and technologies are all poor, and the difference is the equipment. Although the requirements of the oxide ceramics for the sintering equipment are not very high, the requirements of the non-oxide materials for the sintering equipment are much higher. Therefore, at present, these high-end equipments basically can only Rely on imports, the price is very expensive if these aspects can be overcome, I believe we can produce high-end specialty ceramic products, and promote it.
After continuous research and experiment, finally obtained a kind of ceramic thermal shock resistance test method which can overcome the above difficulties, through the combination of experimental test and numerical simulation. The plasma beam is used primarily to rapidly heat the center of an alumina ceramic disk so that a temperature and thermal stress gradient can form, causing damage to the experimental sample. For comparison, a model can be obtained. The conclusion drawn by this simulation method is very consistent with the experimental results, which is very suitable for use.
There is another zirconia ceramic ball insulation, processing precision, hardness, etc. have obvious advantages. Mainly due to the ceramic is a good insulating material, and it is precisely because of the other properties of the product is superior, so it can be finished to meet the needs of different industries.
