Sintering of Aly

[123Cat]

With sintering,,,, the metal is not melted as in casting
Its compressed then heated to below its melt point

Is this right ?

Thats the question

thanks

Sintering is a simple process whereby bulk basalt or a particular mineral or set of minerals in powder form are heated to a high temperature less than the melting point, whereby the particles bond to each other, producing a porous (on a microscopic scale) material. The material usually shrinks significantly, and often the sintering process occurs in a die with a compaction pressure. The vacuum in space generally helps this process. The heat can come from either direct solar energy and/or microwave. Microwave heating allows quicker uniform heating.

Sintering is used for many materials, including metal alloys and ceramics. Sintering is performed at a temperature less than the melting temperature. The mechanism for sintering is diffusion - at high enough temperature, the atoms of a material are mobile and diffuse to minimize surface energy.
