Yttrium Pellets are available from Goodfellow's wide range of metal pellets. Yttrium has a high melting point of 1526°C and is soft and ductile. The pellets can be used in various scientific experiments investigating the properties of rare earth metals. They are also used industrially in alloys and as a protective coating for high-temperature applications. With their high purity and precise dimensions, the Yttrium Pellets from Goodfellow are ideal for research and development purposes.
