(EN) METHOD FOR PRODUCING ZIRCONIUM DIOXIDE NANOPARTICLES IN THE PRESENCE OF AN AMINO ACID
(FR) PROCEDE DE PREPARATION DE NANOPARTICULES DE DIOXYDE DE ZIRCONIUM EN PRESENCE D'ACIDE AMINE
Abrégé
(EN)
The present invention relates to a method for producing zirconium dioxide, ZrO2, nanoparticles by hydrothermal treatment of a zirconium IV compound in the presence of water, at a pH below 7, and of at least one amino acid comprising at least 4 carbon atoms, said amino acid being present in an acid function to amine function ratio greater than or equal to 1. The invention also relates to zirconium dioxide nanoparticles which exhibit a transmittance in the visible spectrum of greater than or equal to 20% at 400 nm and greater than or equal to 95% at 800 nm, measured in water at a concentration of 40% by weight.
(FR)
La présente invention concerne un procédé de préparation de nanoparticules de dioxyde de zirconium, ZrO2, par traitement hydrothermal d'un composé de zirconium IV en présence d'eau, à un pH inférieur à 7, et d'au moins un acide aminé comprenant au moins 4 atomes de carbone, ledit acide aminé présentant un rapport fonction acide sur fonction amine supérieur ou égal à 1. L'invention concerne également des nanoparticules de dioxyde de zirconium, présentant une transmittance dans le visible supérieure ou égale à 20% à 400 nm et supérieure ou égale à 95% à 800 nm mesurée dans l'eau à une concentration de 40% en poids.
