Title (EN) TITANIA COMPOSITE AND PREPARING METHOD THEREOF
(FR) COMPOSITE DE DIOXYDE DE TITANE ET PROCÉDÉ POUR LE PRÉPARER
(ZH) 一种复合二氧化钛及其制备方法
Abstract:
(EN) A titania composite and a preparing method thereof are provided. The titania composite comprises an inner core and a coating film layer, wherein the inner core is a barium sulfate crystal and/or a strontium sulfate crystal, with a subsphaeroidal shape, having a particle size of less than 1 µm and whiteness of more than 98%, and the coating film layer is nano rutile titania. The preparing method thereof comprises the following steps: (a) preparing barium sulfate or strontium sulfate; (b) coating treatment; (c) subjecting the titania composite to a high-temperature heat treatment; and (d) subjecting the titania composite to a post treatment. The subsphaeroidal titania composite is obtained by chemically synthesizing a subsphaeroidal submicron barium sulfate or strontium sulfate and then hydrolyzing and coating thereon to form a coating film layer of titania and make it grow evenly. The particle size of the titania composite is small, and the particle size distribution range of the titania composite is controllable.
(FR) L'invention concerne un composite de dioxyde de titane et un procédé pour le préparer. Le composite de dioxyde de titane comprend un cœur interne et une couche de film de revêtement, le cœur interne étant constitué d'un cristal de sulfate de baryum et/ou d'un cristal de sulfate de strontium, avec une forme sub-sphéroïde, dont la taille de particule est inférieure à 1 µm et la blancheur supérieure à 98 %, et le film de revêtement étant constitué de dioxyde de titane sous forme nano rutile. Le procédé de préparation du composite comprend les étapes suivantes : (a) préparation de sulfate de baryum ou de sulfate de strontium; (b) traitement de revêtement; (c) soumission du composite de dioxyde de titane à un traitement thermique à haute température; et (d) soumission du composite de dioxyde de titane à un post-traitement. Le composite de dioxyde de titane sub-sphéroïde est obtenu par synthèse chimique de sulfate de baryum ou de sulfate de strontium sub-sphéroïde de taille inférieure au micron, puis hydrolyse et dépôt pour former une couche de film de revêtement de dioxyde de titane et en le faisant croître uniformément. La taille de particules du composite de dioxyde de titane est petite, et l'intervalle de distribution de tailles de particules du composite de dioxyde de titane est contrôlable.
