在浆料中添加造孔剂和海藻酸钠模板剂,通过自动滴球固化成型得到湿球,再经干燥、两次焙烧和P FA S化学修饰后,最终得到超疏水ZrO2-SiO2多孔陶瓷微球.同时,使用XRD、SEM、EDS、N2-低温物理吸附仪、压汞、接触角仪以及万能试验机对经1100℃、1200℃和1400℃烧结后的陶瓷微球的结构、形貌、比表面积、表面静态接触角和耐压性能进行表征.结果表明,1200℃烧结温度下的多孔陶瓷微球中微孔—介孔和中孔—大孔比表面积分别高达34.55 m2·g?1和30.98 m2·g?1,对应的孔体积分别为0.248 mL·g?1和0.688 mL·g?1,并具备高达9.2 N耐压的受力强度.该多孔陶瓷微球还展示出优异的疏水性能和高稳定性,其球外表面接...

Wet ceramic spheres were obtained by using auto-drop device with a slurry consisting of pore-forming agent and sodium alginate template,leading to super-hydrophobic ZnO2-SiO2porous ceramic microspheres,after drying,roasting and PFAS chemical modification.Structure,morphology,specific surface area,static contact angle and pressure resistance of the porous ceramic microspheres obtained at 1100℃,1200℃and 1400℃were characterized by using XRD,SEM,EDS,mercury injection,contact angle meter and universal tester.The ceramic microspheres sintered at 1...
