YTTRIA
Yttrium Oxide (Y203)
Yttrium oxide, also known as yttria, is used in a variety of industries in the U.S. The main users of yttria in the U.S. include the electronics, aerospace, and medical industries.
In the electronics industry, yttria is used as a dopant in the production of solid-state electronics, such as computer chips and LED lights. It is also used as a coating for the electrodes of solid oxide fuel cells.
In the aerospace industry, yttria is used as a component of high-temperature materials, such as thermal barrier coatings for jet engine parts. It is also used as a stabilizer for the zirconia ceramics used in aerospace applications.
In the medical industry, yttria is used as a component of dental ceramics, such as crowns and bridges. It is also used in the production of bone cement and as a contrast agent for medical imaging.
Overall, yttria is a versatile material with many different applications, and its usage varies depending on the industry and the specific application.
