Zirocnia Ceramics:
The Zirconia Ceramic centrifugal grouting points into the rotating model Ceramic Plunger to inject the mud, and the centrifugal force generated by the rotating model accelerates the process of the mud dehydration process. The centrifugal grouting has the advantages of uniform thickness and compact body, but the particle size fluctuation cannot be too large, otherwise it will There is an uneven distribution of large particles concentrated on the surface of the mold, resulting in unevenness of the blank and inconsistent shrinkage. The model rotation speed depends on the size of the product, generally less than 100r/min. Figure 3 is a schematic diagram of centrifugal grouting.
Hot pressing sintering (HPS) is a method of hot pressing forming Si3N4 Alumina Zirconia powder and a small amount of additives (such as MgO, Al2O3, MgF2, Fe2O3, etc.) at a pressure of 1916 MPa or more and a temperature of 1600 °C or higher. The hot-pressed sintered Si3N4 ceramics have a strength of up to 981 MPa. The addition and phase composition have a great influence on the properties of the product. Due to the strict control of the composition of the grain boundary phase and the appropriate heat treatment after sintering of the Si3N4 ceramic, Obtaining Si3N4 ceramic materials that do not drop significantly even at temperatures up to 1300 °C (up to 490 MPa), and the creep resistance can be increased by three orders of magnitude. For high temperature pre-oxidation of Si3N4 ceramic materials at 1400-1500 °C Treatment, the Si2N2O phase is formed on the surface Industrial Ceramic of the ceramic material, which can significantly improve the oxidation resistance and high temperature strength of the Si3N4 ceramic. The mechanical properties of the Si3N4 ceramic produced by the hot press sintering method are superior to those of the reaction sintered Si3N4, and the strength and density are high. The manufacturing cost is high, the sintering equipment is complicated, and the dimensional accuracy of the product is limited due to the large shrinkage of the sintered body. It is difficult to manufacture complex parts, and it is only possible to manufacture parts with simple shapes, and the machining of the workpiece is difficult.
