Sintering is a method used to densify powder material through atomic diffusion. Sintering Furnace Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials.The atoms in the materials diffuse across the boundaries of the particles, fusing the particles together and Reduction of the surface oxides from the powder particles in the compact. These steps and the sintering process itself are generally achieved in a single, continuous furnace by judicious choice and zoning of the furnace atmosphere and by using an appropriate temperature profile throughout the furnace. Utilizing a sintering furnace, the green parts are heated to the appropriate temperature to sinter the material. Similar to sintering, pelletizing is another widely used process to agglomerate the iron ore. Sinter plants are usually located near the blast furnace plant, but pelletizing plants are often located near the mining site.

It is obvious that under the sintering pressure of 5.0 GPa, the hardness of the pure tungsten sample increases with the increase of the vacuum sintering temperature. This maximum temperature is roughly in the range of 2050 F to 2150 F (1120 - 1180 C). The sintering process is used to compact a powder into a solid with the application of heat or Electronics Mesh Belt Conveyor Furnace. The tendency of refractory metals to oxidize requires reducing atmospheres or vacuum for sintering. The sintering process is governed by the following parameters: temperature and time, geometrical structure of the powder particles, composition of the powder mix, density of the powder compact, composition of the protective atmosphere in the sintering furnace. Pusher furnaces aka skillet furnaces are represented in many processes.
