In addition, the thermal conductivity of silicon carbide ceramics is also higher, second only to yttria ceramics in ceramics.

Since yttria was a mineral after all and not an oxide, Martin Heinrich Klaproth renamed it gadolinite in honor of Gadolin.

A porous ceramic layer comprised of Yttria partially stabilized zirconia or Ceria-Yttria partially stabilized zirconia is deposited on the metallic layer to impede the flow of heat therethrough.

A corrosion resistant component of semiconductor processing equipment such as a plasma chamber includes a boron nitride/yttria composite containing surface and process for manufacture thereof.

The yttria insulator ring may be located between a ground extension and a plasma generation zone, or gap, of the chamber of the apparatus, as well as between an edge ring and the ground extension.

The overlay shows electrochemical activity of platinum (Pt) nanoparticles on an yttria-stabilized zirconia (YSZ) surface, revealing enhanced activity along the triple-phase boundaries (TPB).

YSZ (yttria-stabilised zirconia) is also a key component of solid oxide fuel cells, a source under development for electricity considered "clean".

AxZir Zirconia discs are partially sintered 3mol% yttria (Y2O3) stabilized zirconia (ZrO2) blanks, which are made from zirconia ceramic powder by cold isostatic pressing and machining process.

Through the years, nano-particle chemistry has enabled Nyacol to diversify their product offering into a range of inorganic materials, including silica, alumina, zirconia, ceria, yttria and oxides of tin and zinc.
