Zirocnia Ceramics:
Disadvantages of hot die casting process: 1. High porosity, relatively few internal defects, low density, relatively poor mechanical properties and performance stability of the product. 2. Dewaxing is required, increasing energy consumption and production time due to dewaxing It is difficult to prepare thick-walled products 3. It is not suitable for the preparation of large-sized ceramic products. 4. It is difficult to manufacture high-purity ceramic products, which limits the application of the process in high-end technology. Application of hot die-casting process: mainly used for the production of small and medium-sized structures and complex structures. Structural ceramics, wear-resistant ceramics, electronic ceramics, insulating ceramics, textile ceramics, heat-resistant ceramics, sealed ceramics, corrosion-resistant ceramics, heat-resistant ceramic products
Atmospheric pressure sintering (PLS) is used to increase the temperature of the sintered nitrogen atmosphere by using the Si3N4 decomposition temperature (usually decomposed at 1800 °C under N2 = 1 atm pressure), and is carried out at a temperature ranging from 1700 to 1800 °C. After atmospheric pressure sintering, the gas pressure sintering is carried out in the temperature range of 1800-2000 ° C. The purpose of the method is to promote the densification of Si3N4 ceramics by gas pressure, thereby improving the strength of the ceramic. The performance of the obtained product is slightly lower than that of hot-pressed sintering. The disadvantages of the method are similar to hot press sintering.
