Erbium oxide

Erbium oxide (CAS 12061-16-4), also known as erbia, is a rare earth oxide used primarily as a pink-to-rose colorant and dopant material across specialty manufacturing sectors. Its stable coloring properties and optical characteristics make it a sought-after input for glass, ceramics, and advanced material formulations for industrial applications.

In cosmetics and personal care, erbia functions as a pigment in mineral makeup, eyeshadow, and blush formulations where a soft pink hue is required for the final product. Glass and specialty optical manufacturers incorporate it to impart a distinctive rose tint to decorative glassware, lenses, and glazes used in high-end manufacturing processes.

In printing inks and packaging coatings, erbium oxide contributes color stability in specialty pigment blends requiring inorganic rare earth colorants for durability and performance. The textile and paper industries use it in dyeing auxiliaries and specialty coatings where conventional organic colorants are unsuitable for high-temperature or chemically aggressive conditions.

Erbium oxide is supplied as a fine powder, typically in high-purity grades ranging from 99% to 99.999% (5N), with purity tier being the primary specification buyers evaluate. Technical and research grades are the most commonly traded forms, with particle size specifications available for application-specific requirements and bulk industrial procurement needs.
