Tungsten trioxide is an inorganic substance with a yellow powder appearance. Its chemical formula is WO3. It is widely used in cemented carbide, fireproof materials, anti-corrosion coatings and other fields. Nano-tungsten trioxide refers to nano-powder of tungsten trioxide, which has the advantages of good durability, high conductivity, and good thermal stability. It is widely used in electronic products, new energy vehicles, environmental protection, photocatalytic materials and other fields.

The main preparation methods of nano-tungsten trioxide include liquid phase method, gas phase method and solid phase reaction method. The liquid phase method can be subdivided into hydrothermal method, precipitation method, sol-gel method, microemulsion method, etc. The liquid phase method can strictly control the size of nanoparticles; the gas phase method refers to the use of vapor deposition technology to produce high purity Nano-tungsten trioxide, this method is widely used in the production process of nano-tungsten trioxide; the solid-phase reaction method refers to calcining the raw materials under high temperature conditions, and finally producing the finished product through solid-phase reaction, cooling, grinding and other processes.

According to the “2023-2028 China Nano-tungsten Trioxide Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Nano-tungsten trioxide has a wide range of applications, including electronic products, new energy vehicles, environmental protection, photocatalytic materials, etc. In the field of new energy vehicles, nano-tungsten trioxide can be used as anode material for lithium batteries of new energy vehicles, which can increase the energy density of the battery and enable the battery to charge and discharge quickly. According to statistics from the China Association of Automobile Manufacturers, my country’s new energy vehicle sales will reach 6.887 million units in 2022, a year-on-year increase of 93.4%. Driven by downstream demand, the development speed of my country’s nano-tungsten trioxide industry will further accelerate.

In recent years, my country’s research and development of nano-tungsten trioxide has become enthusiastic. In 2021, the scientific research team of Lanzhou City University and Xuchang University prepared a quantum dot light-emitting diode using a tungsten trioxide nanocrystal film as a hole injection layer. This product has the advantages of long luminous life, high fluorescence efficiency, and high luminous intensity, and is promising in the future. Widely used in lighting field.

The main manufacturers of nano-tungsten trioxide in my country include Ningbo Jinlei Nano Materials Technology Co., Ltd., Jiangsu Xianfeng Nano Materials Technology Co., Ltd., Shanghai Maoguo Nano Technology Co., Ltd., Shandong Duoju Chemical Co., Ltd., Suzhou Youzirconium Nano Materials Co., Ltd., Xuancheng Jingna Environmental Protection Technology Co., Ltd., etc. At present, my country’s nanotungsten trioxide market competition is relatively fragmented, with small production companies and low industry concentration.

Industry analysts said that after years of development, the maturity of my country’s nano-tungsten trioxide technology has continued to improve, production capacity has rapidly expanded, and output has continued to grow. . As a new type of nanomaterial, nano-tungsten trioxide is widely used in new energy vehicles, environmental protection and other fields. With the accelerated development of downstream industries, my country’s nano-tungsten trioxide market demand is increasingly strong. In the future, as research continues to deepen, the application scope of nano-tungsten trioxide in my country is expected to be further expanded.
