Yttrium Oxide Powder Y2O3 99.999 In Coatings For Semiconductor Production Technology Equipment

Yttrium oxide, also known as yttria, is Y2O3. It is an air-stable, white solid substance. Yttrium oxide is used as a common starting material for both materials science as well as inorganic compounds.

• Density: 2.90 oz/in³
• Melting point: 4,397°F (2,425°C)
• Chemical formula: O₃Y₂
• Average Molar mass: 225.81 g/mol
• Boiling point: 7,772°F (4,300°C)

Application:

Yttrium oxide along with CaO, MgO and BN are considered as candidate materials for insulator coating. Particularly due to its extremely high temperature stability - up to approx. 2,200°C - and its outstanding resistance to alkaline melts with high oxygen affinity, Y2O3 is used in numerous special applications such as in insulators, glass, electrical conducting ceramics, refractories, and stains.

Yttrium oxide because of its properties may also be used as a laminated insulator. Y2O3 is the most thermodynamically stable compound in the oxide group. It is resistant to many reactive molten metals such as titanium or uranium. In its industrial application as a pure ceramic, yttrium oxide is still a relatively new material.

Yttrium oxide is suitable for use in many special applications such as refractory field. In the refractory field, the application range includes use as a compound for applications that require stability at high temperatures. For example, they can be made for graphite in nuclear technology as coating material. Because yttrium oxide forms a solid solution with uranium oxide, it is also employed as a diluting agent of uranium oxide for nuclear fuel rods.
