Abstract
Nanosized zirconium dioxide has wide and significant uses.Varieties of preparation and recent new application of nanosized zirconium dioxide are reviewed on the basis of new progress and developing trends at home land and abroad.Zirco-nium sol were prepared by using the gel-sol method with ZrOCl2 ·8H2O.By the various kinds of measurement tech-niques,determined a whole rational program of preparing zirconium sol,using the gel-sol method,while the ammonia was slowly driped to the buffer solution as precipitator.After suction filtration and rinse,defined quantity of electrolyte was add-ed to redistribute the filter mass,heat the miscible liquids at 75 ℃ with 5~12 h,the uniform and stable nano-scale zirconi-um sol was generated.The influence of different concentration of precursor solution,value of pH and buffer solution and other factors on stability and size of zirconium sol were investigated and analyzed.Via the TEM,nanoparticle size analyzer, TG-DSC graph of the study on the products,the results showed that the particle of the sol was appeared at columnar and umbellar.The size is about 12 to 15 nm.The zirconium sol was separated and existed stability at the range of pH value from 0.8 to 1.4.Then zirconium react with ekonol,ekonol shows an obvious improvement in anti-heat.关键词
