Ho2O3

Notas

Holmium(III) oxide (Ho2O3), also referred to as holmia, is a rare-earth oxide characterized by significant paramagnetic properties. Within the field of ceramics and glass science, it functions primarily as a specialized colorant. Its inclusion in glass compositions creates distinct optical effects, notable for producing a series of sharp, well-defined absorption bands across the visible light spectrum. Due to these specific spectral characteristics, holmium-doped glass serves as a standard reference material for the calibration of optical spectrophotometers. Like other trivalent lanthanides, it is typically extracted from mineral deposits in conjunction with related elements such as dysprosium and erbium, requiring complex separation techniques to achieve purity.
