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).
