摘 要: 以聚丙烯酸(polyacrylic acid, PAA)做分散剂和粘接剂,采用注浆成型工艺和真空烧结技术制备了光学质量良好的钇铝石榴石(yttrium aluminum garnet, YAG)陶瓷托槽。通过扫描电子显微镜(scanning electron microscope, SEM)、流变仪分别对粉体、托槽坯体及浆料进行表征。结果表明:用PAA质量分数为2%、固相含量为60%(质量分数)的YAG浆料可以得到均匀的坯体,再经过两步真空烧结制备出高质量的陶瓷托槽。采用PAA做分散剂和粘接剂注浆成型是一种很有发展潜力的透明陶瓷成型方法。
关 键 词: 无机非金属材料;钇铝石榴石陶瓷托槽;注浆成型;聚丙烯酸;黏度;真空烧结

Abstract: High-quality yttrium aluminum garnet (YAG) ceramics brackets were fabricated by vacuum sintering technique and the slip casting using polyacrylic acid (PAA) as dispersant and binder. The powders, suspension and brackets green body were characterized by scanning electron microscope (SEM) and Rheometer. The results showed that the good green bodies could be obtained from slurries with 2% mass fraction of PAA and with 60% (mass fraction) of solid content. High-quality YAG ceramics brackets were fabricated by two-step vacuum sintering technique. It can be expected that the slip casting method with PAA as dispersant and binder is a very promising way for the ceramic brackets forming.
Key words: inorganic nonmetallic material; yttrium aluminum garnet ceramic brackets; slip casting; polyacrylic acid; viscosity; vacuum sintering
