| Abstract | ||
| Zirconia fibers have been prepared by convertional method using cotton threads impregrated in zirconium oxychloride solution ( ZrOCl2. 8H2O ). X-ray diffraction shows the crystallinity of zirconia and optical microscopy shows the fibers fabrication. Differnet percentage ( 2 ,4 ,8 , 10 and 12 ) of prepared zirconia fibers mixed with ZnO powder. All the specmen sintered at 1250 °C for 2hrs. Physical properties (density and volume shrinkage) were measured and Mechanicl properties (Vicker ̉s hardness,fracture strength and fracture toughness by indentation method ) were calculated, 10% of fiber content has the maximum values for these properties for the composite. | ||
