For materials that are difficult to sinter, a process called liquid phase sintering is commonly used. Materials for which liquid phase sintering is common are Si 3 N 4, WC, SiC, and more. Liquid phase sintering is the process of adding an additive to the powder which will melt before the matrix phase.
Liquid phase sintering is a sintering technique that uses a liquid phase to accelerate the interparticle bonding of the solid phase. In addition to rapid initial particle rearrangement due to capillary forces, mass transport through liquid is generally orders of magnitude faster than through solid, enhancing the diffusional mechanisms that drive densification.

Iron powder is commonly used for sintering. Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes are sometimes used to reduce or eliminate the need for subtractive processes in manufacturing, lowering material losses and reducing the cost of the final product.

In this step, an organic solvent dissolves most of the plastic binding material. Consequently, the green parts transition into "brown" parts. The debinding process eliminates excess plastic, leaving behind a structure of metal powder. [2] Sintering: The brown parts, now washed, are transferred to a sintering furnace. This furnace adheres to a ...
Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting.
BERLIN (Reuters) -Three parties in the eastern German state of Thuringia joined forces on Thursday to keep the poll-topping Alternative for Germany out of power, electing as state premier a ...
Up-to-date ceramic technology involves invention and design of new components and optimization of production processes of complex structures. Ceramics can be formed by a variety of different methods which can be divided into three main groups, depending on whether the starting materials involve a gas, a liquid, or a solid.
