12055-62-8 Usage

Description

Holmium oxide occurs in nature, usually associated with small quantities of other rare-earth oxides. Commercial applications of this compound have not been explored fully. It is used in refractories and as a catalyst. Characteristic spectral emission lines of holmium oxide glass are used to calibrate spectrophotometers.

Chemical Properties

Holmium oxide (Ho2O3), also known as Holmia, is a light yellow powder that is one of the most paramagnetic substances known. Holmium oxide glass has been used as a wavelength standard for over four decades. It has a number of desirable features that have made it a commonly used wavelength standard. It does not induce a slit positioning error as atomic emission lamps may. It is also compact, easy to use, and most importantly, stable over long periods of time.the use of filters made of holmium oxide glass allows the calibration of wavelength for a spectrophotometer over a broad range.

Uses

Holmium(III) oxide acts as colorants which is used for cubic zirconia and glass, as a calibration standard for optical spectrophotometers, as a specialty catalyst, phosphor and a laser material. Holmium Oxide, also called Holmia, has specialized uses in ceramics, glass, phosphors and metal halide lamp, and dopant to garnet laser. Holmium can absorb fission-bred neutrons, it is also used in nuclear reactors to keep atomic chain reaction from running out of control. Holmium Oxide is one of the colorants used for cubic zirconia and glass, providing yellow or red coloring. It is also used in Yttrium-Aluminum-Garnet (YAG) and Yttrium-Lanthanum-Fluoride (YLF) solid-state lasers found in microwave equipment (which are in turn found in a variety of medical and dental settings).

Preparation

Holmium oxide is prepared by thermal decomposition of carbonate, oxalate, hydroxide, nitrate, sulfate, or any oxo salt of holmium: Ho2(CO3)3 →Ho2O3 + 3CO2 Ho2(SO4)3 →Ho2O3 + 3SO3 The oxide may be obtained by direct combination of elements at elevated temperatures. The element in massive form, however, reacts slowly at high temperatures.

Chemical Properties

slightly beige solid

Physical properties

Yellow cubic crystal; density 8.41 g.cm3; melts at 2,415°C; insoluble in water; dissolves in acids (with reactions).

Uses

Holmium(III) oxide iacts as colorants which is used for cubic zirconia and glass, as a calibration standard for optical spectrophotometers, as a specialty catalyst, phosphor and a laser material.

Uses

Refractories, special catalyst.
