Atmospheric pressure sintering is a traditional preparation process of AlN ceramics. In the normal pressure sintering process, the green body is not affected by external pressure, and is transformed from an aggregate of powder particles into a grain combination only by heating under normal pressure. Atmospheric pressure sintering is the simplest and most extensive sintering method.
Vacuum Sintering Furnace(AlN),it is used to improve the density of AlN ceramics by enhancing the sintering temperature in a slightly positive pressure or inert atmosphere. It also can be used for sintering of molding parts made by AlN powder and metal additives
● Pressureless sintering;
● The holding time is longer, but its equipment and process are simple and easy to operate. , Under heating, the aggregate of powder particles is transformed into a grain combination. Atmospheric pressure sintering is the simplest and most extensive sintering method. The general temperature range of atmospheric pressure sintered aluminum nitride ceramics is 1600-2000 ℃;
