Abstract

The invention relates to the technical field of tobacco carriers, in particular to an Al 2 o 3 Preparation methods and applications of porous ceramics. It uses magnesium raw material, aluminum raw material, and pore-forming agent as raw materials, and sequentially includes steps of mixing, molding, drying, and sintering; the pore-forming agent includes inorganic carbon coated with starch; in the sintering step, sequentially includes: a. To 220-300°C, keep warm for more than 30min; b. raise the temperature to above 1500°C, keep warm for more than 30min. In the present invention, the starch-coated inorganic carbon is used as a pore-forming agent. During the sintering process, starch is used to form pores at a low temperature, and the pores are supported by the inorganic carbon to prevent the pores from collapsing and closing, which can effectively increase the apparent porosity of the porous ceramics obtained by sintering.

Description

technical field

[0001] The invention relates to the technical field of tobacco carriers, in particular to an Al 2 o 3 Preparation methods and applications of porous ceramics. Background technique

[0002] E-liquid or flavors and fragrances have high requirements on the carrier, and the carrier for tobacco generally has the following problems: 1. The preparation process is complicated and the production cost is high; 2. The miscellaneous smell or foreign matter is produced by heating; 3. The ability to absorb and store liquid is not enough; 4. The thermal conductivity is not high, and the heat cannot be quickly transferred to the storage liquid when heated, so that the storage liquid cannot be quickly atomized, which affects the user's consumption experience.

[0003] Although the carrier in the prior art can realize the atomization of e-liquid or flavor and fragrance at a certain temperature, there are still some problems in its application in the actual atomization system...
