Abstract： |
The invention provides a carbon nano tube / nano zirconium oxide composite toughening material and its preparing process, wherein the material is CNTs with nano zirconium oxide particles adhered on the surface, and the preparing process comprises, preparing CNTs suspending liquid, charging zirconium source and strong base to form CNTs / zirconium hydroxide colloid, heating the CNTs / zirconium hydroxide colloid to dehydrate the colloid, then transforming zirconium hydroxide into zirconium oxide under high temperature protection state, finally obtaining the carbon nano tube / nano zirconium oxide composite toughening material with controllable nano grade grain diameter, when used for alumina ceramics, the fracture toughness property can be improved appreciably. |
