A Novel Route for the Easy Production of Thermochromic VO₂ Nanoparticles.

ABSTRACT: In this work, a simple, fast and dry method for the fabrication of a thermochromic product with a high load of VO₂ (M1) consisting of the controlled heat treatment of pure vanadium nanoparticles in air is presented. After a complete design of experiments, it is concluded that the most direct way to attain the maximum transformation of V into VO₂ (M1) consists of one cycle with a fast heating ramp of 42 °C s^-1 , followed by keeping 700 °C for 530-600 seconds, and a subsequent cooling at 0.05 °C s^-1 . Careful examination of these results lead to a second optimum, even more suitable for industrial production (quicker and less energy-intensive because of its lower temperatures and shorter times), consisting of subjecting V to two consecutive cycles o
