Porous ceramic, preparation method thereof and aerosol generating device
The invention relates to a porous ceramic, a preparation method thereof and an aerosol generation device, the preparation method of the porous ceramic material comprises the following steps: mixing a ceramic preparation material, a gel mixture, a dispersant and an initiator to obtain a precursor, the mass of the initiator is 0.1-3 wt% of the total mass of the gel mixture, and the mass of the precursor is 0.1-3 wt% of the total mass of the gel mixture; the mass of the dispersing agent is 0.1 wt%-2.0 wt% of the total mass of the ceramic preparation material; carrying out molding treatment on the precursor to obtain a green body; and carrying out sectional heating treatment on the green body, and sintering to obtain the porous ceramic material. According to the prepared porous ceramic material, the aperture gradient of pores from the atomization surface to the oil guide surface is increased, the large aperture near the oil guide surface is beneficial to oil guide, the small aperture near the atomization surface is beneficial to oil locking, oil leakage is effectively avoided, meanwhile, oil leakage and unsmooth oil guide caused by the fact that the aperture near the oil bin part is too small are effectively avoided, and therefore core pasting is avoided.
本申请涉及一种多孔陶瓷及其制备方法、气溶胶产生装置，多孔陶瓷材料的制备方法包括如下步骤：将陶瓷预备料、凝胶混料、分散剂和引发剂混合得到前驱体，所述引发剂的质量为所述凝胶混料总质量的0.1wt％～3wt％，所述分散剂的质量为所述陶瓷预备料总质量的0.1wt％～2.0wt％；将所述前驱体进行成型处理得到坯体；将所述坯体进行分段式升温处理、烧结处理得到多孔陶瓷材料。本申请制备的多孔陶瓷材料从雾化面至导油面孔隙的孔径梯度增大分布，导油面附近的大孔径利于导油，雾化面附近的小孔径利于锁油，有效避免漏油，同时还有效避免靠近油仓部位的孔径过小造成漏油和导油不畅，从而避免造成“糊芯”。
