1 This reaction distinguishes the members of the yttria group from most of the other earths.
2 Aim: Newer zirconia materials may have greater strength degradation under cyclic fatigue with increased yttria and cubic content.
3 Here is an egg-shaped bulb, shown in Fig 19, containing some pure yttria and a few rough rubies.
4 The alkaline earths are instances of this kind of reaction, also glucina oxide of cerium, tantalic and titanic acids, yttria and zirconia.
5 A group of so-called "rare-earths," among which are zirconia, thoria, ceria, erbia, and yttria (these are oxides of zirconium, etc.)
6 With yttria in a vacuum tube, the point of maximum phosphorescence, as I have already pointed out, lies on the margin of the dark space.
7 See how well the rubies and yttria phosphorescence shows under molecular bombardment, at an internal pressure of 0.00068 millimeter, or 0.9 M.
8 Yttria is found in gadolinite and some other rare minerals.
9 25, has a flat aluminum pole, in the form of a disk, at each end, both coated with a paint of phosphorescent yttria .
