The melting behavior of aluminum nanoparticles having an oxide passivation layer is examined using a differential scanning calorimetry (DSC). Both broad and narrow size-distributed particles are studied, and the weight-average particle radius ranges from 8 to 50. nm.. With decreasing particle size, the melting response moves towards lower temperatures and the heat of fusion decreases.

Smelting is a process of applying heat to ore in order to extract out a base metal. It is a form of extractive metallurgy . It is used to extract many metals from their ores, including silver, iron, copper, and other base metals .

Consider melting or smelting your gold, silver, and other metals yourself! But first understand that there is a big difference between melting and smelting. Melting means to change something from a solid to a liquid by the application of heat.

The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold does at temperatures equal to or greater than the melting point of gold. The impure gold is therefore melted and gaseous chlorine is blown into the resulting liquid.
