Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...

The Sintering Process in Powder Metallurgy | GE Additive

Transient liquid phase sintering. Transient liquid phase sintering may involve the addition of copper powder to iron powder to counter the natural pole shrinkage that would otherwise occur during the sintering process. At regular sintering temperatures, the copper fully melts, and the molten copper infuses and swells the iron particles.

Sintering in the Powder Metallurgy Process - pm-review

Transient liquid phase sintering. In a compact that contains only iron powder particles, the solid state sintering process would generate some shrinkage of the compact as the sintering necks grow. However, a common practice with ferrous PM materials is to make an addition of fine copper powder to create a transient liquid phase during sintering.
