The invention further providesporous ceramic and application thereof in an electronic cigarette atomizer. The porous ceramic has good compression resistance and porosity.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to porous ceramics and a preparation method and application thereof. Background technique [0002] Porous ceramics have the characteristics of high porosity, good surface activity, high temperature resistance, and corrosion resistance. Therefore, they have the functions of filtration and separation, sound absorption and noise reduction, and catalytic reactions. They are widely used in the fields of building materials, catalyst carriers, and biomedicine. application. E-cigarettes are electronic products that mimic cigarettes and have the same look, smoke, taste and feel as cigarettes. It is a product that turns nicotine and other substances into vapor through means such as atomization, and then allows users to smoke. The electronic cigarette atomizer is the core component of the electronic cigarette, which plays the role of storing smoke liquid and generating smoke. In re...
