Terminology

Atomization is a manufacturing method that creates metal powder by using gas or water to spray molten metal. [1]

A flaked copper and zinc alloy powder. This powder is used as a metal powder pigment that provides a gold color and metallic brilliance. An alloy of copper and zinc is conventionally called brass, but in fields that print with gold colors, copper-zinc alloy powders have historically been referred to as gold or bronze powders. This nomenclature continues to this day.

Chemical reduction is a reduction technique that uses a reducing agent, instead of using hydrogen directly. [2]

compactibility is an important powder property for powder metallurgy. It refers to the ease or difficulty of molding a substance, including the minimum pressure required to provide the molded item with sufficient strength, and the properties of the molded item necessary to withstand handling after molding—especially to ensure that corners and protrusions are not easily damaged. [3]

This manufacturing method deposits powders on a cathode in a electrolysis tank. The main advantage is high purity. [1]

This type of alloy powder consists of individual particles with the same homogeneous chemical composition as the overall bulk powder.[3][4]

This refers to a flaked metal powder's tendency to float to the surface of a coating, similar to floating leaves covering a water surface.

Metallic brilliance or gloss can be obtained from bronze or other flaked metal powders used as a metal powder pigment in gold inks by coating the flakes with fatty acids.

This technology is used to manufacture metal powders or create materials or products by molding and sintering metal powders or a mixture of metal and non-metal powders. [3]

Partially alloyed powders are alloy powders that include particles that are not fully alloyed. [3][4]

This term refers collectively to all insulating substrates that include a pattern of conductors, used to connect between electronic devices, printed on or inside that substrate based on a circuit design, but before any semiconductors, electronic components, or other devices mounted on the board. [5]

These terms indicate the color of gold pigments, where pale gold refers to a pigment color with a reddish-gold color produced from an alloy of 90 % copper and 10 % zinc. Rich gold refers to a metal powder pigment with a color similar to pure gold that is produced from an alloy of 75 % copper and 25 % zinc.

Sintering generally refers to compressing primarily metal or ceramic powders into a solid form at temperatures below their melting point. [3]

Stamping using a stamp mill to flatten metal powder into flakes, which involves pounding the metal powder with multiple metal pestle-like rods, until the particles are spread out into thin flakes.
