通过黏度、表面张力、密度及粒度测试等手段研究了球磨剂、球磨时间、pH值、添加剂等因素对纳米氧化锆水悬浮液稳定性的影响。结果表明:球磨时间2h,球磨剂与氧化锆质量比为3.5%,添加剂可用乙二醇,悬浮液pH值为10.0,氧化锆粒径小于15nm时,纳米氧化锆水悬浮液可稳定30天。 The effects of milling agent, milling time, pH, additives and other factors on the stability of nanosized zirconia aqueous suspension were studied by means of viscosity, surface tension, density and particle size measurement. The results showed that when the ball milling time was 2h, the mass ratio of milling agent to zirconia was 3.5%, ethylene glycol was used as the additive, the pH value of the suspension was 10.0, and the particle size of zirconia was less than 15nm, the aqueous suspension of zirconium oxide could stabilize for 30 days.
