Yttrium Powder

Yttrium powder is a finely divided metallic powder with a typical particle size under 10 microns. Yttrium is a rare earth metal valued for its high melting point and corrosion resistance. As part of our extensive range of powders, it comes in 9 variations based on purity and particle size specifications. This versatile powder has applications in lasers, phosphors, ceramics, and superconducting materials where its unique properties are required. Yttrium's ability to absorb a large amount of hydrogen also makes it useful for hydrogen storage applications.
