Ultrafine particles or micronization of elements
is known as elemental micron powders. Granulometry makes it into fine elemental
powder. However, it has poor stability and volatility of essential oils leading
to redox processes and enzymatic degradations. Due to its instability, it is
available as freeze-ground powders. Alloy microparticles are obtained through
the process of alloying. It involves the melting of certain elements, which are
based on two or more components where one is a metal. Therefore, the alloy
microparticle processes metallic characteristics, which can be lead, copper,
aluminum, iron, and various other metals.
