The performance of zirconia ceramic products is susceptible to the following factors:
1. The influence of raw materials
High quality zirconia powder is selected, and the performance factors and content of zirconia powder have important effects on zirconia ceramics.
2. The influence of sintering
Zirconia ceramic green is compact at high temperature, zirconia ceramic products sintering temperature, time will affect the performance of zirconia ceramic, and zirconia ceramic products densification rate, structure depends on the product sintering process.
3, the impact of raw material particle size
In the production process of zirconia ceramics, the particle size of raw materials will affect the performance factors of products. Only when the raw materials are delicate enough, the finished products are likely to form microstructure, so that the products have good wear resistance. The same is true for zirconia ceramics, so the finer the particle of zirconia powder, the greater the activity, which can promote sintering, reduce the risk of product cracking, and improve the fracture toughness of zirconia ceramics preparation and the wear resistance of products.
4. The influence of molding method
In the preparation of zirconia ceramics, if the manufacturer wants to obtain high quality zirconia ceramic embryos, the molding method of the product is the key factor. The molding of zirconia ceramics generally adopts dry pressing, isostatic pressing, hot die casting and other methods. Zirconia ceramic manufacturers mainly use grouting and hot die casting technology for products with complex shape, and can use dry pressing molding for products with simple shape. Therefore, the choice of molding method of zirconia ceramics also affects the quality of products.
In summary, it can be seen that the performance of zirconia ceramics is easily affected by raw materials, sintering, raw material granularity, molding methods and other factors. In addition, zirconia ceramics are also easily affected by the holding time, additives, salt selection and calcination conditions. If zirconia ceramic manufacturers want to manufacture excellent performance zirconia ceramic plates, it is necessary to conduct comprehensive consideration from the particle size of raw materials, forming methods, sintering temperature, time and other aspects.
