Pressing And Sintering Of Powder Parts
Powder Sintering . Powder sintering involves raising the temperature of the green compact, (pressed powder part), to a certain level and keeping it at that temperature for a certain amount of time. The sintering temperature is usually between 70% and 90% of the melting point of the powder metal. This will cause bonding mechanisms to occur between powder particles .

Industrial: Powder Metallurgy
The resulting powder is milled, classified and blended to the desired specifiions. The purity of the product depends on the purity of the oxide since there is no refining during the reduction process. Generally, the powders produced by this method tend to be porous and have high apparent densities and green strength.

Powder Metallurgy For Manufacturing
Some tests unique to powders may also be used. For example, an iron powder may have an unknown percent of iron oxide, (Fe 2 O 3). A test sample of the iron powder is taken and exposed to a stream of hydrogen. Weight loss that occurs in the sample is measured. From this, the percentage of iron oxide present in the powder can be calculated.
