The classification of metal powder can be differentiated according to its preparation method, particle shape, size, chemical composition, etc. The following are some common ways to classify metal powder:
1. Classification according to preparation method: Metal powder can be divided into gas phase metal powder and liquid phase metal powder. Gas phase metal powder is to condense or evaporate metal or alloy gas into solid metal particles by physical or chemical methods. Liquid phase metal powder is prepared by melting metal or alloy.
2. Classification according to particle shape: Metal powder can be divided into spherical powder, flaky powder, fibrous powder, and dendrites and nanowires synthesized by metal gas phase chemical reaction.
3. Classification according to size: Metal powder can be divided into micron powder, nanometer powder and submicron powder.
4. Classification according to chemical composition: Metal powder can be divided into eight categories: copper-based, iron-based, aluminum-based, magnesium-based, nickel-based, cobalt-based, titanium-based, zirconium-based, etc.
In addition, the classification of new metal powder materials includes high entropy alloy powder, ultra-fine grain metal material, aerogel metal material, biodegradable metal powder material, etc.
