Abstract
Description
technical field
[0001] The invention belongs to a vanadium dioxide nanometer powder material and a preparation method thereof, in particular to a composite doped vanadium dioxide nanometer powder material and a preparation method thereof. Background technique
[0002] VO 2 It is a typical phase-change compound, which undergoes a first-order phase transition at around 68°C. Along with the phase transition, the resistivity, magnetic susceptibility, optical refractive index, transmittance, and reflectance undergo a sudden change, and the phase transition process is reversible. Experiments have shown that doping can change VO 2 The phase transition temperature, expanding VO 2 field of application, therefore, for doped VO 2 The research on its preparation method has very important value.
[0003] The Chinese patent application with the application number 95196132.2 discloses a vanadium dioxide particle and its preparation method. The vanadium di...
