Ytterbium(III) Oxide is a highly insoluble thermally stable Ytterbium source, which is a chemical compound with the formula Yb2O3. It is one of the more commonly encountered compounds of ytterbium. It is usually used for glass, optic and ceramic applications.
Yttrium Oxide, also known as Yttria, is an excellent mineralizing agent for spinel formation. It is an air-stable, white solid substance. It has a high melting point(2450°C), chemical stability, low coefficient of thermal expansion, high transparency for both visible (70%) and infrared (60%) light, low cut off energy of photons. It is suitable for glass, optic and ceramic applications.
