Process Shaping powder materials
Powder technology is a family of net- or near-net-shaping methods used to shape metals and ceramics from powders.
The amount of waste material is very low and costly post-machinings are often avoided.
The technology involves the following steps.

1)The starting powder is prepared;
2)The powder is formed into a desired shape (green body), which can be furtherly worked; 3)The green body is sintered at a high temperature (densification).
4)The sintered compact is finished into the final shape.

Frequently a combination of high-temperature and pressure (hot pressing) is used.
