In this study, we wanted to improve the properties of the composite material by using both boron oxide as a sintering aid to improve the densification of zirconia, to lower the sintering temperature and to increase the thermal shock resistance of the composite structures and, the yttrium oxide as a stabilizer to produce defective oxides with oxygen vacancies in the crystal structure.

Individual heavy rare earth element grades were 0.03 kg/t europium oxide, 0.27 kg/t gadolinium oxide, 0.05 kg/t terbium oxide, 0.29 kg/t dysprosium oxide, 0.06 kg/t holmium oxide, 0.15 kg/t erbium oxide, 0.02 kg/t thulium oxide, 0.11 kg/t ytterbium oxide, 0.01 kg/t lutetium oxide and 1.88 kg/t yttrium oxide. The $8 million 2011 budget includes 12,000 meters of drilling, subsurface work via a proposed adit in the Dotson zone, metallurgical work via bench-scale testing, environmental baseline work and a 60 ton bulk sample from the Dotson Zone.
These knife blades are made of top-quality ceramic: 95 percent zirconium oxide and 5 percent yttrium oxide. This material provides a very hard, sharp edge that rarely needs sharpening.
The coated metal tape is baked at 500[degrees]C, which evaporates the alcohol and converts the yttrium acetate into yttrium oxide. As it dries, the coating shrinks, following the original substrate contours.
METHODS: To test the hypothesis, we incubated HAECs for 1-8 hr with different concentrations (0.001-50 [micro]g/mL) of iron oxide ([Fe.sub.2][O.sub.3]), yttrium oxide ([Y.sub.2][O.sub.3]), and zinc oxide (ZnO) nanoparticles and subsequently measured mRNA and protein levels of the three inflammatory markers intracellular cell adhesion molecule-1, interleukin-8, and monocyte chemotactic protein-1.
Yttrium Oxide partially stabilized Zirconia belongs to a new class of ceramics exhibiting an improved toughness when compared to alumina.
Iron and steel operations have resorted to tough materials such as zirconia oxide, or aluminum oxide filters compounded with zirconia oxide, calcium oxide, yttrium oxide, mullite, spinels and other ceramics for improved thermal shock capabilities.
