Abstract
The present application discloses a method for preparing porous glass for an electronic cigarette, comprising the following steps: heating quartz glass to a molten state for granulation; mixing boron-silicon powder and quartz glass granules, and heating a mixture to a temperature between 600° C. to 900° C. to cover peripheries of the quartz glass granules with the boron-silicon powder; and sintering the quartz glass granules covered with boron-silicon in a preset mold to obtain the porous glass for the electronic cigarette. The technical solution according to the present application can greatly improve the smoking taste of the electronic cigarette.
