Abstract
Ceramic materials with relatively high resistance to wetting by various liquids, such as water, are presented, along with articles made with these materials. The oxide materials described herein as a class typically contain europia (Eu2O3). The oxides may further contain other additives, such as oxides of gadolinium (Gd), samarium (Sm), dysprosium (Dy), or terbium (Tb). In certain embodiments the oxide, in addition to europia, further comprises ytterbia (Yb2O3), lanthanum (La), praseodymium (Pr), or neodymium (Nd).
Claims6
A material comprising:
- an oxide comprising
- at least about 50 mole % europia;
- and
- samaria, terbia, or dysprosia;
- wherein the material contains up to about 25 atom % of tetravalent cations relative to the total amount of cations present in the material.
A material comprising:
- a B-type monoclinic oxide comprising ytterbia and europia;
- wherein the oxide contains up to about 25 atom % of tetravalent cations relative to the total amount of cations present in the material.
