Document Type and Number:
WIPO Patent Application WO/2017/086068
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a process for producing particles comprising vanadium dioxide which have a small average particle diameter and low unevenness in particle diameter. The process for producing particles comprising vanadium dioxide is one for producing particles comprising vanadium dioxide which has thermochromic properties, and is characterized by comprising: a step in which at least water and a raw material containing vanadium (V) are mixed to prepare a liquid reaction mixture; a step in which the liquid reaction mixture is heated from ordinary temperature to a hydrothermal reaction temperature at a heating rate in the range of 5.8-15.0 °C/min; and a step in which the liquid reaction mixture heated to the hydrothermal reaction temperature is made to undergo a hydrothermal reaction.
