Zeygerovanie

Zeigering (from German Seigern - to separate ) - in non-ferrous metallurgy, the process of separation of an alloy into its constituent parts.

Zeygerovanie based on the difference in the melting temperature of the components of any alloy . Since the temperature of each element is different, when the alloy is slowly heated, metals and mixtures with lower melting temperatures are melted from it first.

With increasing temperature, more refractory elements melt, etc.

For sintering, inclined hearth reflective furnaces are used.

Example: a more fusible metal , for example, lead , is released at temperatures above 327 ° C , and a refractory metal , for example, copper or silver , remains solid at this temperature.
