Porous ceramics preparation method, porous ceramics and application thereof
The present invention relates to a porous ceramics preparation method, porous ceramics and application of the porous ceramics in electronic cigarettes. The porous ceramics preparation method comprises the following steps: uniformly mixing amorphous silica, alumina and ferric oxide to obtain a mixture; calcining the mixture at a temperature of 1000 C DEG-1400 C DEG for 0.5-3 hours to obtain a precursor; grinding the precursor to obtain precursor powder, wherein the mixture comprises, by mass percentage, 80%-98% of the amorphous silica, 1%-10% of the aluminum oxide, and 1%-10% of the ferric oxide; uniformly mixing the precursor powder, sodium silicate, and a pore-forming agent to obtain a premix; uniformly mixing the premix and water for compression molding to obtain a green compact; keeping the green compact at a temperature of 200 C DEG-600 C DEG for 1-6 hours; and then sintering the kept green compact at a temperature of 700 C DEG-1200 C DEG for 0.5-3 hours to obtain the porous ceramic.
