Explanation

It refers to the sintering of one or more powder, and there is no liquid phase in the sintering process. solid state sintering can be divided into two types: unit system solid state sintering and multi-element system solid state sintering. Unit system solid state sintering: the solid state sintering process of pure metals (such as refractory metals and pure iron soft magnetic materials) or compounds (A1203, B4C, BeO, etc.) at temperatures below melting point. Multi system solid state sintering: a sintering system consisting of two or more components. The solid state sintering process is carried out below the melting point temperature of the low melting point component. The sintering process includes the formation of bonding surface, the growth of sintering neck, pore sealing and spheroidization stages.
