Usage

Description

Yttrium oxide, also known as Yttria, is a white powder with a body-centered cubic structure. It has a high melting point of 2,436°C, is insoluble in water, and soluble in dilute acids. Yttrium oxide is an excellent mineralizing agent for spinel formation and possesses high chemical stability, low coefficient of thermal expansion, and high transparency for both visible (70%) and infrared (60%) light.

Uses

Used in Gas Lighting Industry
Yttrium oxide is used as a component in the manufacture of gas mantles for its extremely high temperature stability.
Used in Inorganic Synthesis
Yttrium oxide serves as a raw material or source of Yttrium for the production of Yttrium compounds.
Used in Ceramic Industry
Yttrium oxide is used as a raw material or additive in the manufacture of pure ceramics, thanks to its extremely high temperature stability and outstanding resistance to alkaline melts. It is also utilized in the production of other ceramic materials such as Si3N4, AlN, ZrO2, etc., and in multilayer ceramic capacitors.
Used in Display Materials
Used as an Insulator
Yttrium oxide is employed as an effective component in insulator coatings and laminated insulators due to its extremely thermodynamically stable nature and resistance to many reactive molten metals.
Used in Nuclear Technology

Yttrium oxide serves as a main component in coating materials for high-temperature applications, leveraging its extreme thermodynamic stability.
Used in Manufacturing Steel, Non-Ferrous Alloys, and Iron
Yttrium oxide is used as an additive in these processes due to its extreme thermodynamic stability.
Used in the Production of IR and UV Translucent Glass
Yttrium oxide is utilized in the creation of high-temperature superconductors and as an additive in the preparation of permanent magnets.
Used in the Preparation of Solid-State Laser Material
Yttrium oxide acts as a dopant in lasers with ytterbium, allowing for efficient operation in both continuous and pulsed regimes.
Used in the Manufacture of Yttrium Iron Garnets
Yttrium oxide is used as a raw material or source of Yttrium to produce Yttrium-Iron-Garnets, which are very effective microwave filters.
Used in Ultrafast Sensors
Yttrium oxide is employed as an additive in ultrafast sensors used in g-ray and x-rays.
Used in Paints and Plastics
Yttrium oxide is used as an additive to decrease UV degradation.

Preparation

Yttrium oxide is produced as an intermediate in recovery of yttrium from xenotime and monazite (See Yttrium, Recovery). The oxide is produced after separation of rare earth sulfates obtained from digesting the mineral with sulfuric acid on a cation exchange bed, precipitating yttrium fraction as oxalate, and igniting the oxalate at 750°C. Yttrium oxide also may be obtained by thermal decomposition of yttrium nitrate.

Flammability and Explosibility

Nonflammable

Safety Profile

A poison by intraperitoneal route. See also YTTRIUM and RARE EARTHS.
