Gadolinium Oxide Powder / Gd2O3 Powder (99.95%, 5um)

Gadolinium Oxide Powder

Introduction:

Gadolinium oxide powder also known as gadolinium(III) oxide, is a rare earth metal oxide compound composed of the element gadolinium (Gd) and oxygen. It is typically produced by calcining gadolinium compounds, such as gadolinium carbonate (Gd₂(CO₃)₃) or gadolinium hydroxide (Gd(OH)₃), in a high-temperature furnace. The resulting powder is white, odorless, and can appear slightly gray or yellow depending on its purity..

Properties of Gadolinium Oxide Powder:

Physical Properties:

Appearance: Fine, white powder that may have a yellowish or gray tint depending on the purity level.

Density: Gadolinium oxide has a relatively high density of 7.41 g/cm³, which contributes to its mechanical strength in certain applications.

Melting Point: Gadolinium oxide has a high melting point around 2,400°C, which makes it suitable for high-temperature environments.

Magnetic Behavior: As gadolinium is a paramagnetic element, Gd₂O₃ exhibits magnetic properties and is used in magnetic materials.

Solubility: It is insoluble in water but soluble in acids, forming gadolinium salts like gadolinium chloride (GdCl₃).

Chemical Properties:

Stability: Gadolinium oxide is chemically stable under normal conditions and does not react easily with air, although it can react with moisture at high temperatures to form gadolinium hydroxide.

Reactivity: It can react with acids to form soluble gadolinium salts, such as gadolinium nitrate or gadolinium chloride.

Fluorescence: Gadolinium oxide exhibits luminescence when exposed to ultraviolet light, making it useful in phosphorescent applications.

Optical and Electronic Properties:

Gadolinium oxide can transmit infrared radiation, which is useful in optical and infrared applications.

It is a non-conductive material, which makes it useful in electronic and electrical insulation applications.
