METHOD FOR PREPARING POROUS CERAMIC MATERIAL, POROUS CERAMIC MATERIAL AND USE THEREOF

摘要

Provided are a method for preparing a porous ceramic material, a porous ceramic material prepared by the method and a use of the material in an electronic cigarette atomizer. The preparation method comprises the following steps: a silicate raw material and a pore-forming agent are mixed to obtain a premix, wherein the silicate raw material comprises sodium silicate and other compounds, which are at least one of an oxide, a nitride, and a carbide; the premix is dried to obtain a silicate aggregate; the silicate aggregate and a binder are subjected to mixing to obtain an injection raw material, wherein by mass percentage, the silicate aggregate is 50% to 60%, and the binder is 40% to 50%; the injection raw material is injection moulded to obtain a biscuit; and the biscuit is successively processed by degumming and calcining to obtain the porous ceramic material.
