What Is Sintering?

Sintering is a process of compacting and forming a solid mass of material by heating it to a temperature below its melting point. This process is commonly used in the production of ceramics, metals, and other materials. The word sinter comes from the German word "sintern," which means "to heat without melting.".

Solid Phase Sintering

Solid-state sintering is the bonding and densification of particles by the application of heat below the melting point of a material. During sintering, the free surface area of the compact decreases, and this is normally accompanied by an increase in the density. As such, it represents an essential part of powder processing as a high density is ...

Sintering is a thermal treatment process in which a powder or a porous material, already formed into the required shape, is converted into a useful article with the requisite microstructure. Sintering can be classified as solid-state, viscous, liquid-phase, and pressure-assisted (or pressure) sintering. This article provides information on the ...

What Is The Sintering Process? | Explaining the Stages Of Sintering …

Sintering, by definition, is a process used in manufacturing to compact solid materials. The resulting product is a harder, stronger, more durable mass due to the high heat and pressure applied forcing the atoms of the material into tighter bonds with each other. Most manufacturing processes use a sintering furnace that can provide the ...

Sintering mechanics of ceramics: a short review

The sintering stress is defined by the force acting on a cross section A of the unit cell [13, 14]: S s = F A . (Force balance method) (6) The sintering stresses defined by three different methods are exactly the same for porous materials in equilibrium [14]. The sintering stress of periodical porous structure was calculated numerically.
