Description

technical field

[0001] The invention relates to the preparation of vanadium dioxide powder in the fields of chemical industry and materials, in particular to doped vanadium dioxide powder and film, and a preparation method and application thereof. Background technique

[0002] At present, the world's energy demand is increasing by 2% per year, and about 30% of this energy is consumed in buildings. Taking my country as an example, building energy consumption has accounted for 27.6% of the total energy consumption of the society, and the resulting energy consumption and environmental pollution have continued to intensify. Glass is the main channel for heat and light energy exchange between buildings and the outside world. Heat exchange through glass windows accounts for 48% and 71% of the total energy exchange in winter and summer, respectively. Therefore, the development of energy-saving glass is expected to greatly reduce building energy consumption.
