Title:
METHOD FOR PRODUCING VANADIUM DIOXIDE-CONTAINING PARTICLES, AND VANADIUM DIOXIDE-CONTAINING PARTICLES
Document Type and Number:
WIPO Patent Application WO/2018/020983
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for producing vanadium dioxide-containing particles having a narrow range of transition temperatures. This method for producing vanadium dioxide-containing particles is a method for producing thermochromic vanadium dioxide-containing particles, and is characterized by comprising: a step for preparing a reaction solution containing a vanadium-containing compound, a non-vanadium element A selected from among elements belonging to Group V or VI of the Periodic Table of the Elements, an element B selected from among elements belonging to Group XIII or XIV of the Periodic Table of the Elements, and water; and a step for subjecting the reaction solution to a hydrothermal reaction to form vanadium dioxide-containing particles, wherein, with respect to 100 atom% of vanadium, the total amount of element A added is in the range of 0.05-20 atom% and the total amount of element B added is in the range of 0.5-20 atom%.
