本文报道了氧化钇透明陶瓷的胶体加工。以柠檬酸三铵（TAC）为分散剂，将工业氧化钇粉末分散于去离子水中，制备了氧化钇纳米粉体的水悬浮液。通过沉降试验、Zeta电位和粘度测定，研究了吸附分散剂、悬浮介质pH值和固体含量对悬浮液稳定性的影响。添加1.0重量%的TAC足以稳定Y2 O3悬浮液。将制备的固体含量为15vol%的胶体悬浮液通过离心铸造固结成绿色压坯，并测量了真空烧结样品的透光率。所制备的陶瓷在800 nm处具有最高的线透射率~55%。氧化钇，透明陶瓷，胶体加工
Colloid processing of transparent yttria ceramics has been reported in this work. Aqueous suspensions of nano yttria powder were prepared by dispersing commercial powder into deionized water with triammonium citrate (TAC) as the dispersant. Effects of adsorbed dispersant, pH of suspending medium and solid loadings on the stability of the suspensions were characterized by means of sedimentation test, Zeta potential and viscosity measurements. Addition of 1.0 wt% TAC was enough to stabilize Y2O3 suspensions. The prepared colloidal suspensions with 15vol% solid loadings were subsequently consolidated into green compacts via centrifugal casting and the transmittance of the sample sintered in vacuum was measured. Ceramics prepared has an highest in line transmittance of~55% at 800 nm . Index Terms—yttria, transparent ceramics, colloidal processing
