The zirconia-based antibacterial denture material has good antibacterial effect and high strength.

Abstract: Disclosed are a glass ceramic material, a preparation method thereof, and a denture. The glass ceramic material includes the following components by mass percentage: 58% to 72% of SiO2, 0% to 4% of Al2O3, 0% to 5% of Na2O, 3% to 8% of K2O, 8% to 17% of Li2O, 2.5% to 5% of P2O5, 0% to 2% of MgO, 0% to 2.5% of B2O3, 0% to 5% of ZnO and 0% to 3% of ZrO2. In the present application, by optimizing the composition and ratio of the glass ceramic material, and combining with a matching process system, it is possible to control the formation of lithium disilicate while the crystallinity of lithium metasilicate glass ceramic can be improved without an introduction of a high ratio of zirconia content, thereby improving the grinding performance of the glass ceramic. The present application is applicable to the field of material technology.

Abstract: Disclosed are a glass ceramic composition, a preparation method and application thereof. The glass ceramic composition according to the present application includes: 58% to 72% of SiO2; 0% to 4% of Al2O3; 0% to 5% of Na2O; 3% to 8% of K2O; 8% to 17% of Li2O; 2.5% to 5% of P2O5, 0% to 2% of MgO, 0% to 2.5% of B2O3; 0% to 5% of ZnO; and 0% to 3% of ZrO2. It is possible to prepare such lithium metasilicate glass ceramic with a crystal phase of lithium metasilicate, a crystallinity of greater than 50%, a grain size of 30 nm to 60 nm and a hardness of 500 kgf/mm2 to 590 kgf/mm2. The composition does not require an introduction of a high proportion of zirconia content, and can be ground to a thickness of 0.2 mm without edge collapse.

Abstract: An atomizer includes a liquid storage shell, an ultrasonic atomizing core, a liquid transporting cotton, a cooling block, and an end cap. The liquid storage shell surrounds the liquid storage cavity and the functional cavity which are isolated from each other, wherein the liquid storage cavity is used for storing liquid. The ultrasonic atomizing core is assembled in the functional cavity. The liquid transporting cotton is connected to the ultrasonic atomizing core and inserted into the liquid storage cavity, so as to transport the liquid in the liquid storage cavity to the ultrasonic atomizing core. The cooling block is attached on one side of the ultrasonic atomizing core. The cooling block has an atomizing hole and an oil return hole. The end cap is connected to one end of the liquid storage shell to seal the liquid storage cavity and the functional cavity.
