Abstract[English]
[Problem] There is provided an inorganic oxide particle-containing composition exhibiting excellent dispersion stability of inorganic oxide particles and excellent salt tolerance. [Solution] An inorganic oxide particle-containing composition, wherein, in image analysis of a frozen sample by cryo-transmission electron microscope observation, the sample being prepared by adding the inorganic oxide particle-containing composition to 4% by mass of salt water such that the concentration of inorganic oxide particles is 0.5% by mass, and rapidly freezing with liquefied ethane, a coefficient of variation, which is a value obtained by dividing a standard deviation of areas of Voronoi partition regions based on an inorganic oxide particle distribution in a region of interest (ROI) by the arithmetic mean of the areas, is 0.1 to 0.7.[French]
Est divulguée une composition contenant des particules d'oxyde inorganique présentant une excellente stabilité de dispersion de particules d'oxyde inorganique et une excellente tolérance au sel. Dans la composition contenant des particules d'oxyde inorganique, lors de l'analyse d'image d'un échantillon congelé par observation au microscope électronique à cryo-transmission, l'échantillon étant préparé par ajout de la composition contenant des particules d'oxyde inorganique à 4 % en masse d'eau salée de sorte que la concentration de particules d'oxyde inorganique est de 0,5 % en masse, et une congélation rapide avec de l'éthane liquéfié étant réalisée, le coefficient de variation, qui est une valeur obtenue par division d'un écart-type de zones de régions de partition de Voronoï en fonction de la répartition de particules d'oxyde inorganique dans une région d'intérêt (ROI) par la moyenne arithmétique des zones, est compris entre 0,1 et 0,7.
