Vanadium dioxide (VO2) is a kind of chemical raw material with special properties, and its unique thermochromic and photoelectric properties make it widely used in many fields. In the field of raw materials for chemical production, the upstream and downstream related products of vanadium dioxide mainly include the following categories:

1. Upstream raw material

The production of vanadium dioxide mainly uses vanadium pentoxide (V2O5) as raw material and is obtained through reduction reaction. Therefore, vanadium pentoxide is the main upstream raw material of vanadium dioxide. In addition, auxiliary materials such as reducing agents and catalysts need to be used in the production process.

2. Downstream Products

(1) Smart Window Coating

Vanadium dioxide has thermochromic properties and can be used in smart window coatings. In the summer high temperature, the vanadium dioxide in the coating will be transformed into a metallic state, reducing the transmission of infrared rays, thereby reducing the indoor temperature; and in the winter low temperature, the vanadium dioxide is transformed into an insulating state, allowing the transmission of infrared rays. Keep the indoor temperature. Therefore, smart window coating is one of the important downstream products of vanadium dioxide.

(2) Optoelectronic devices

vanadium dioxide has a wide range of applications in the field of optoelectronic devices due to its photoelectric properties. For example, vanadium dioxide can be used to manufacture optical switches, optical modulators and other devices to control and adjust the optical path. In addition, vanadium dioxide can also be used to make solar cells to improve the efficiency of solar energy collection and utilization.

(3) catalyst

Vanadium dioxide has a certain catalytic activity and can be used for the preparation of catalysts. For example, vanadium dioxide can be used as an oxidation catalyst for the oxidation of organic matter; it can also be used as a selective catalytic reduction catalyst for the treatment of pollutants such as nitrogen oxides in industrial waste gas.

(4) The energy storage material

the phase change properties of vanadium dioxide so that it can be used as an energy storage material. In the process of phase change, vanadium dioxide can absorb or release a large amount of heat, so as to realize the storage and release of energy. This property makes vanadium dioxide have a wide range of applications in the field of energy storage.

In summary, the upstream and downstream related products of vanadium dioxide in the field of chemical production raw materials include vanadium pentoxide, smart window coatings, optoelectronic devices, catalysts and energy storage materials. These products play an important role in practical applications and provide strong support for the development of various fields.
