Гранулометрический состав порошка определяли методами статического лазерного рассеяния и оптической микроскопии. Методом электрофореза с титрованием измеряли зависимость величины дзета-потенциала суспензии частиц диоксида циркония от рН среды. Исследовано влияние показателя кислотности на стабильность суспензии в процессе измерения. Показано, что стабильная суспензия может быть получена смещением pH среды диспергирования как в область «кислых», так и «щелочных» значений, а также добавлением поверхностно-активных веществ, например, Dolapix CE 64.</p></abstract><trans-abstract xml:lang="en"><p>Dispergation conditions of zirconia doped with 3 % mol yttrium oxide are specified. Grain-size distribution of the power particles is determined using static laser scattering and optical microscopy. Electrophoresis with titration is used for measuring the dependence of zeta-potential of zirconia suspension on öl value. The effect of the acidity on the stability of suspension during measurement is considered. It is shown that stable suspension can be obtained by shifting pH value of dispersion media both to acidic or alkali regions and also by adding surface active substances (e.g., Dolapix CE 64).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>static laser scattering</kwd><kwd>particle size distribution</kwd><kwd>isoelectric point of zirconia</kwd><kwd>stabilization of suspensions</kwd><kwd>метод статического лазерного рассеяния</kwd><kwd>изоэлектрическая точка диоксида циркония</kwd><kwd>гранулометрический анализ</kwd><kwd>стабилизация суспензий</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lange F.
