Description

Yttrium Oxalate CAS NO 126476-37-7 is a high-purity inorganic salt of yttrium, a critical rare earth element. This compound serves as a vital precursor material for the synthesis of advanced ceramics, phosphors, and specialty catalysts. It is essential for manufacturers and R&D facilities in the electronics, lighting, and chemical processing industries seeking consistent quality and reliable supply for high-performance applications.

Application

• As a key precursor for the synthesis of yttrium oxide (Y₂O₃) and other yttrium-based compounds via thermal decomposition.
• In the production of phosphors for cathode ray tubes (CRTs), fluorescent lamps, and LED lighting, where it acts as a host material.
• For manufacturing specialty ceramics and ceramic composites, including yttria-stabilized zirconia (YSZ) for thermal barrier coatings and solid oxide fuel cells.
• As a catalyst or catalyst precursor in petrochemical refining and organic synthesis processes.
• In optical glass and fiber fabrication to modify refractive index and thermal properties.
• For research and development of new materials in electronics, superconductors, and laser crystals.
• As a starting material in the synthesis of yttrium aluminum garnet (YAG) crystals used in lasers and scintillators.
