Abstract

The invention relates to a porous ceramic raw material, porous ceramic as well as a preparation method and application thereof, wherein the porous ceramic raw material comprises the following components in percentage by mass: 40%-80% of aluminum oxide, 1%-20% of silicon dioxide, 1%-20% of titanium dioxide and 1%-20% of a burning promoting agent. The 40%-80% Of aluminum oxide, the 1%-20% of silicondioxide, the 1%-20% of titanium dioxide and the 1%-22% of the burning promoting agent are used as the raw materials to prepare the porous ceramic with the pore size of 10 microns to 50 microns and porosity reaching 30%-70% without addition of a pore forming agent, the porous ceramic is smooth in oil guide, a heating circuit is plated on the surface of the porous ceramic, the heating circuit cannot permeate into pores to cause the situation that the heating circuit is burnt due to short circuit or uneven heating, the porous ceramic can replace oil guide cotton as an oil storage and oil guide function part of an atomizing core, the smoke volume and the taste can be greatly improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of ceramic materials and technology, in particular to porous ceramic raw materials, porous ceramics and their preparation methods and applications. Background technique [0002] E-cigarette is an electronic product that imitates cigarettes. It has the same appearance, smoke, taste and feeling as cigarettes. It is a product that turns e-liquid into steam by means of atomization and other means, and allows users to smoke. [0003] The vaporizer core of the electronic cigarette is the core component of the electronic cigarette, which determines the size and taste of the smoke produced by the electronic cigarette. The traditional electronic cigarette atomizer core uses stainless steel as the main material, and the oil-guiding cotton and heating wire inside constitute the atomization inner chamber, but the problem caused by the oil-guiding cotton atomizer core is that the atomizer is easy to burn, and the overall...
