Ceramic atomizing core and preparation method thereof
The invention belongs to the field of functional ceramics, and particularly relates to a porous ceramic atomization core for an electronic cigarette atomization device and a preparation method thereof. The ceramic atomizing core is prepared from the following raw materials in percentage by weight: 60-90% of a framework raw material, 10-30% of a sintering agent and 0-30% of a pore forming agent, wherein the framework raw material is SiO2 particles, the sintering agent is mixed powder composed of sodium phosphate, active Al2O3, micro-powder SiO2, potassium borate and calcium fluoride, and the pore-forming agent is at least one of an organic pore-forming agent, graphite, sawdust and rice hull. According to the invention, the atomization core ceramic can be sintered at a lower temperature by utilizing the formation of the in-situ sintering aid (glass phase), and higher strength can be formed only by sintering in an air environment, so that the oxidation of the atomization core metal resistor disc caused in the high-temperature sintering of the traditional ceramic and the corrosion reaction with the ceramic can be effectively avoided; and therefore, the stability of the resistance of the resistor disc is ensured, and the yield of the ceramic atomizing core in the production process is further improved.
本发明属于功能陶瓷领域，尤其涉及电子烟雾化装置用多孔陶瓷雾化芯及其制备方法。所述陶瓷雾化芯由如下重量比的原料组成：60～90%的骨架原料，10～30%的烧结剂，0～30%的造孔剂；所述骨架原料为SiO2颗粒，所述烧结剂为磷酸钠、活性Al2O3、微粉SiO2、硼酸钾及氟化钙组成的混合粉，所述造孔剂为有机造孔剂、石墨、锯末及稻壳中的至少一种。本发明利用原位烧结助剂（玻璃相）的形成使雾化芯陶瓷可在较低温度下进行烧结，且只需在空气环境中烧结即可形成较高的强度，能够有效避免雾化芯金属电阻片在传统陶瓷高温烧结中引起的氧化及与陶瓷的腐蚀反应，从而保证了电阻片电阻的稳定，进一步提高陶瓷雾化芯生产过程中的良品率。
