Abstract

The invention relates to a preparation method of a high-toughness nano ceramic powder material for an oral cavity and belongs to the technical field of medical materials. The preparation method is characterized in that molybdenum powder is deposited into a ceramic preparation mold and is subjected to melting and cladding modification; ternary metal silicide Mo2SiZr has high rigidity and an inter-atom bonding property of a metal bond and an atom bond, so that the ternary metal silicide Mo2SiZr is difficultly suffered from metal adhesion and deformation when the ternary metal silicide Mo2SiZr isin contact with surfaces of other metal parts and has frictional wear; the wear-resisting properties and mechanical properties of nano ceramic powder are effectively improved; nano zirconium oxide modified composite ceramic powder is adopted; a method for preparing single-phase gel is adopted, and common sediment of mixed liquid of two phases is obtained through changing the pH value of a solution; a prepared sediment material has excellent bonding performance; the toughening and modification degree of zirconium oxide in the technical scheme on the material is effectively improved, and the bonding strength and mechanical properties of the technical scheme are improved to the certain extent.

Description

technical field [0001] The invention relates to a preparation method of a high-toughness nano porcelain powder material for oral cavity, belonging to the technical field of medical materials. Background technique [0002] Teeth are one of the vital organs of the human body and play a very important role. In our country, due to the lack of health awareness in the early years, the protection of teeth is very poor. Statistics show that the problems of dental caries, periodontitis and various types of tooth loss in our country are serious. For example, among people over 60 years old, the prevalence rate of teeth is 79.42%; among people over 70 years old, the prevalence rate of teeth reaches 100%. Among the young and middle-aged people, there are not a few people who suffer from dental diseases. Moreover, studies have shown that dental deformity not only affects oral function and appearance, but also affects individual social and psychological adaptation. More and more people p...
