Yttria (yttrium oxide, Y2O3) is a rare-earth ceramic which exhibits both exceptional plasma resistance and an aptitude for high-temperature applications. Yttria is often used to stabilize other ceramic compositions like zirconia.
CoorsTek Exyria™ yttria can be formed into both solid parts and coatings for parts requiring exceptional corrosion resistance. Applying a PlasmaResist™ coating to compatible ceramic and metal components creates a corrosively inert barrier of pure yttria.
