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 one or more of ytterbia (Yb2O3) and 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 the ytterbia and/or europia, further comprises lanthanum (La), praseodymium (Pr), or neodymium (Nd).
