Preparation method of porous ceramic, porous ceramic, atomizing core, electronic cigarette and medical equipment
The invention provides a preparation method of porous ceramic, the porous ceramic, an atomizing core, an electronic cigarette and medical equipment, and the preparation method of the porous ceramic comprises the following steps: placing a prefabricated part with a grid structure in a chemical vapor infiltration furnace, and introducing a precursor and hydrogen to perform deposition reaction so as to deposit SiC ceramic on the surface of the prefabricated part and in grids; after the deposition reaction is finished, carrying out sintering reaction on the prefabricated part deposited with the SiC ceramic to remove the prefabricated part and prepare the porous ceramic; wherein the temperature of the deposition reaction ranges from 900 DEG C to 1050 DEG C, and the time ranges from 20 h to 40 h; the prefabricated member comprises carbon fibers; the precursor comprises one or more of alkyl silane and alkyl chlorosilane. By means of the method, directional preparation of the porous ceramic pore structure can be achieved, the pore diameter and distribution uniformity of the formed pore structure can be adjusted according to the prefabricated part, and meanwhile the formed porous ceramic is high in mechanical property, so that the formed porous ceramic is good in atomization consistency when serving as an atomization core body, the risk of oil leakage or core pasting can be reduced, and safety and reliability are effectively improved.
本申请提供了一种多孔陶瓷的制备方法及多孔陶瓷、雾化芯、电子烟和医疗设备，多孔陶瓷的制备方法包括：将具有网格结构的预制件置于化学气相渗透炉中，通入前驱体和氢气进行沉积反应，以在预制件的表面和网格中沉积SiC陶瓷；沉积反应结束后，对沉积SiC陶瓷后的预制件进行烧结反应，以去除预制件，制备多孔陶瓷；其中，沉积反应的温度为900℃‑1050℃，时间为20h‑40h；预制件包括碳纤维；前驱体包括烷基硅烷和烷基氯硅烷中的一种或多种。通过该方法可实现多孔陶瓷孔结构的定向制备，形成的孔结构孔径及分布均匀性可根据预制件进行调整，同时形成的多孔陶瓷力学性能强，从而使得其作为雾化芯本体雾化一致性好，可降低漏油或糊芯的风险，且安全可靠性得到有效提高。
