More Information
Summary: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 hi
