Abstract
Ceramic materials with relatively high resistance to wetting by various liquids, such as water, are presented, along with articles made with these materials, methods for making these articles and materials, and methods for protecting articles using coatings made from these materials. One particular embodiment is an article that comprises a coating having a surface connected porosity content of up to about 5 percent by volume. The coating comprises a material that comprises a primary oxide and a secondary oxide, wherein (i) the primary oxide comprises a cerium cation, and (ii) the secondary oxide comprises a cation selected from the group consisting of the praseodymium and neodymium.
