Non-wettable materials, manufactured products with the help of these, and such items manufacturing process.

The invention relates to ceramic materials with a relatively high resistance to wetting by various liquids such as water, articles (200) made with these materials, methods of making such articles, and materials and methods for protected articles with coatings made from these materials. One embodiment comprises a material comprising a primary oxide and a secondary oxide, whose primary oxide comprises cerium and hafnium oxide and the secondary comprises a secondary oxide cation selected from the group consisting of cations rare earth, yttrium and scandium. Another embodiment consists of a material comprising a primary oxide and a secondary oxide, whose primary oxide comprises cerium or hafnium and the secondary oxide comprises (i) praseodymium or ytterbium and (ii ) another cation selected from the group consisting of cations of rare earths, yttrium and scandium.
