Lutetium(III) Oxide
Lutetium(III) Oxide (Lu2O3), also known as lutecia, is a white solid and a cubic compound of lutetium. It is a highly insoluble thermally stable Lutetium source, which has a cubic crystal structure and available in white powder form. This rare earth metal oxide exhibits favorable physical properties, such as a high melting point (around 2400°C), phase stability, mechanical strength, hardness, thermal conductivity, and low thermal expansion. It is suitable for specialty glasses, optic and ceramic applications. It is also used as the important raw materials for laser crystals.
