Hot isostatic pressing sintering refers to the process of sintering densification of ceramic powder, billet or prefired body through the combined action of high temperature and isotropic high-pressure gas. Suitable for manufacturing complex shape products, can improve the density and performance of products.

Hot isostatic pressing sintering (also known as high temperature isostatic pressing sintering, HIP for short) is a process in which materials (powder, blank or sintered body) are subjected to isostatic pressure in the heating process, and the densification of materials is promoted by the combined action of high temperature and high pressure. Hot isostatic sintering furnace is mainly used in the field of powder metallurgy at first. With the continuous improvement of the temperature and pressure that can be achieved by the equipment, it has been successfully applied to the high temperature sintering in the field of ceramics.

The characteristics of hot isostatic sintering furnace are as follows: the material with uniform microstructure, fine grain and complete compact can be prepared at low sintering temperature. Products with complex shapes can be prepared, especially in the preparation of nanomaterials, the powder requirements are not high, even the serious agglomeration of powders can also be used for the preparation of nano ceramics.

The technological advantages of cold isostatic pressing sintering furnace:

(1) Reduce sintering temperature and shorten sintering time;

(2) Reduce or do not use sintering additives;

(3) Improve ceramic performance and reliability;

(4) It is convenient to manufacture products with complex shapes.
