Explanation
At present, the method of obtaining dense and complex sintering body through high-temperature sintering under pressurized nitrogen or inert atmosphere is mainly applied to the sintering of SbNi. It is difficult to obtain dense materials by reactive sintering, and it is impossible to produce complex sintering body by hot m sintering. Although the pressureless sintering method can produce dense and complex Si3N4 sintered bodies. However, under nitrogen atmosphere and sintering temperature of 1650 ° C, it will decompose into Si and N2, so a lot of additive must be added.
