Water resistant ceramic articles |
| abstract |
A zirconia ceramic article is exposed to water at at least 60{C. At least the surface of the article which is exposed to water is prepared by forming an aqueous suspension containing particulate zirconia and particulate yttria, agitating the suspension in a bead mill for at least 2 minutes using a mixing medium having an average particle size of from 0.2 mm to 3 mm, separating and drying the mixed particulate material so formed, shaping said mixed particulate material into a green body and sintering said green body at a temperature in the range 1200{C to 1450{C. The amount of yttria used is at least 4 molar per cent with respect to zirconia and less than 1 per cent alumina by weight with respect to zirconia is present in the green body when said body is sintered. The articles mentioned include components of internal combustion engines e.g. valve guides, valves and valve seats. |
