5、 Xijuan and Men Jiaming( Product and Technology Develop ing Centre of Yizheng Chemical Fibre Co., L td)ABSTRACT: Thedispersion and stability of TiO2 suspension, thestatus of TiO2 particles in thePET chips werestud-ied by means of particle size analyser and the electron microscope. The dispersion of TiO2 is largely connected with dis-persant and electrolyte. The conjugated grains in PET chips are formed of TiO2 congeries particles.SubjectTerms: titanium dioxide; dispersion; particle size214 .=As
