Microporous ceramic, ceramic heating element and preparation method and application thereof

Abstract

The invention relates to a microporous ceramic, a ceramic heating element and a preparation method and application thereof. The preparation method of the microporous ceramics comprises the following steps: mixing raw materials to obtain a mixture, wherein, in terms of mass percentage, the raw materials include the following components: 50% to 70% of mullite, 5% to 20% % sintering aid and 20% to 40% pore-forming agent, the sintering aid is glass powder with a melting point less than or equal to 500°C, the pore-forming agent is fibrous, and the length of the pore-forming agent is 100 microns to 200 microns, The diameter is 40 microns to 60 microns; molding the mixture to obtain a green body; sintering the green body to obtain microporous ceramics. The microporous ceramics prepared by the above preparation method have both high ventilation porosity and high strength.

Description

technical field

[0001] The invention relates to the field of ceramic materials, in particular to a microporous ceramic, a ceramic heating element and a preparation method and application thereof. Background technique

[0002] The atomizing heating element is one of the core components of the electronic cigarette. Compared with the traditional glass fiber cotton winding heating element, the new microporous ceramic heating element consists of heating wire wrapped around the microporous ceramic or printed resistance paste on the surface of the microporous ceramic The composition has the advantages of strong lipophilicity, uniform heating, high temperature resistance, and no dry burning. However, the current microporous ceramic heating element still has the problems of low air porosity and low strength, which makes microporous ceramics easy to drop powder. Seriously affect the taste and bring bad experience to consumers. Contents of the invention
