Yttrium is a gray-black metal with the chemical symbol Y. It is the first rare earth metal element discovered and has ductility.

Yttrium is widely used in industry. It can be used as a yttrium phosphor to produce red color on TV screens. It is also used in filters for certain rays, superconductors and super alloys, and special glasses. Yttrium is resistant to high temperature and corrosion, and can be used as a cladding material for nuclear fuel. Yttrium and a variety of ammonia-carboxyl complexing agents can form stable chelate; neodymium-containing yttrium aluminum garnet is an excellent laser material, yttrium iron garnet is an excellent laser material, yttrium iron garnet and yttrium aluminum garnet are new types of magnetism material.
