Porous ceramic, preparation method and heating body thereof
The invention relates to a porous ceramic, a preparation method and a heating body thereof. The preparation method of the porous ceramic comprises the following steps: mixing raw materials and a poreforming agent, and molding to obtain a green body; wherein the raw materials comprise the following components in percentage by mass: 15%-50% of Si3N4 powder and 50%-85% of Si powder; and sintering the green body in a nitrogen atmosphere to obtain the porous ceramic. The prepared porous ceramic has a fibrous tissue structure and a structure similar to that of a cotton core, so that the taste can be improved; meanwhile, the porous ceramic with the fiber structure has the strength of the ceramic, can be easily prepared into a specific shape, and is convenient to assemble and automatically produce.
本发明涉及一种多孔陶瓷、制备方法及其发热体，多孔陶瓷的制备方法包括以下步骤：将原料和造孔剂混合后成型，得到坯体；按照质量百分含量计，所述原料包括15％～50％的SiN粉和50％～85％的Si粉；将所述坯体在氮气气氛下烧结处理，得到多孔陶瓷。制备得到多孔陶瓷具有纤维组织结构并与棉芯具有类似结构的多孔陶瓷，能够提升口感；同时纤维结构的多孔陶瓷又具备陶瓷的强度，并且容易制备成特定的形状，便于装配和自动化生产。
