Multi-elements oxides are based on two or more elements having an oxide with them. The micron powder for order of these elements is considered as a multi-element oxide micron powder which includes calcium zirconium oxide micron powder, caesium tungsten oxide micro powder, etc. These micron powders range from 10 µm to 100 µm, having ultrafine particles: oxygen and electronegative elements bond with an electropositive element. Multi-element oxide micron powder is used in the research of new proprietary technologies along with its application at a commercial scale.
