1. Character: White amorphous powder. Monoclinic and cubic structures with rare earth Sesquioxide
2. Melting point (℃): 2339
3. Boiling point (℃): 3900
4. Solubility: insoluble in water, soluble in organic acids, and able to easily absorb water and carbon dioxide in the air. When reacting with ammonia, precipitates a hydrate of gadolinium.
Inhalation of gadolinium containing dust can lead to occupational pneumoconiosis. Staff should take proper precautions. Store in a well ventilated and dry place. Attention should be paid to moisture prevention to prevent packaging damage.
In the glass industry, Gadolinium(III) oxide is specially used as a component of high refractive index glass. Gadolinium(III) oxide is used together with lanthanum to help change the vitrification zone and improve the thermal stability of the glass. Nuclear industry is used for Control rod of nuclear reactors, neutron absorbing materials in atomic reactors, magnetic bubble materials, intensifying screen materials, etc. Gadolinium(III) oxide can also be used to manufacture capacitors, X-ray intensifying screens and gadolinium gallium garnet materials.
Gadolinium Oxide, also called Gadolinia, is used for making optical glass and Gadolinium Yttrium Garnets which have microwave applications. High purity of Gadolinium Oxide is used for making phosphors for colour TV tube. Cerium Oxide (in the form of Gadolinium doped ceria) creates an electrolyte with both high ionic conductivity and low operating temperatures that are optimal for cost-effective production of fuel cells. It is one of the most commonly available forms of the rare earth element Gadolinium, derivatives of which are potential contrast agents for magnetic resonance imaging.
Gadolinium oxide Gd2O3 is used as YAG YIG yttrium aluminum and yttrium iron garnet doping agent, sensitized fluorescent material in medical equipment, nuclear reactor control material, raw material for the preparation of metal gadolinium, magnetic bubble material and optical prism additive.
Gadolinium oxide is used as an admixture of yttrium aluminum and yttrium iron garnet, sensitized fluorescent material in medical devices, nuclear reactor control material, raw material of gadolinium metal, magnetic bubble material and optical prism additive, etc.
Function of Gadolinium Oxide
Used in making dyes, rubber vulcanization accelerator, medicines, pesticides fungicides urea-formaldehyde resin, amino resin, ethylene diamine, metal chelating agent, EDTA, etc
Application of Gadolinium Oxide
1.Used as a color TV set red phosphors activator, high pressure mercury lamp with fluorescent powder.
2. Used in making dyes, rubber vulcanization accelerator, medicines, pesticides fungicides urea-formaldehyde resin, amino resin, ethylene diamine, metal chelating agent, EDTA, etc.
3. Used as fiber protein such as solvent.
