Yttrium Aluminate (Y3Al5O12) Powder

Yttrium aluminate (Y₃Al₅O₁₂) is also commonly known as yttrium aluminum garnet (YAG). The crystal structure of YAG is in the cubic crystal category. Yttrium aluminate powder is usually found in the form of a white powder. YAG is an important ceramic material due to its high strength and low creep rate at high temperatures and excellent optical properties. YAG shows thermal stability up to its melting point which is around 1970°C. In most of the practical applications, yttrium aluminate is used as a host material for ions such as neodymium (Nd), erbium (Er), and cerium (Ce). This material is a refractory, hard oxide ceramic that does not damage easily. YAG has optical applications in active optical filters, solid-state lasers, fluorescent materials, and phosphor powders for cathode ray tubes. It is also a promising high-temperature engineering material for insulating or refractory coatings. Alternatively, YAG can be used as a co-catalyst in photocatalytic applications.
