摘要：

Stabilizating properties of carboxymethyl cellulose (CMC) towards nano-zirconia (n-ZrO2) and alumina (Al2O3) were studied using spectrophotometric, turbidimetric and zeta potential measurements. The obtained results prove that CMC might be successfully used as a stabilizer of nano-zirconia, however, its stabilizing properties are much lower in the case of the alumina + containing systems. Due to the fact that CMC is an anionic polymer the influence of not only the polymer concentration but also of pH on stability of the metal oxide suspensions was studied. It turned out that the CMC concentration has larger influence on stability of the metal oxide suspensions than pH. In order to estimate the stabilization mechanism in the studied systems the adsorption of CMC on both oxides was conducted using the spectrophotometric method confirmed by FTIR. The obtained results could find practical applications particularly in the fields of ceramics and catalysis.
