Monoclinic tungsten trioxide is one of the crystal structure of tungsten trioxide. According to the researchers, they have studied the crystal structure of tungsten trioxide at room temperature by the X-ray oscillation method.

Yellow tungsten oxide is a well-known γ-ray shielding material with the chemical formula of WO3. It has been reported that WO3 can be compounded with natural rubber (NR) to obtain NR-WO3 composite materials. Some experts adopt hydrothermal method to synthesize Bi2WO6 nanoparticles and obtain WO3 and Bi2O3 particles with similar particle size by ball milling. And they fill these particles into natural rubber with a total mass fraction of 30% to prepare NR-Bi2WO6, NR-WO3 and NR-Bi2O3 composite material.

Tungsten oxide is developed as a battery electrode. It has been reported that tungsten oxide electrode material enables ultra-fast charging and discharging. So, it is often used as an anode material for lithium ion batteries. And it has a wide range of applications where a large current or capacity is required, such as uninterruptible power supplies (UPS), large current sources, and power supply stabilizers, etc. Also, it has applications with a focus on energy regeneration properties such as elevators, micro/mild hybrid vehicles and trains.

As a radiation shielding material, Er2O3-WO3-epoxy resin can reduce the damage of radiation to human body, equipment and environment. Some experts have prepared Er2O3-WO3-epoxy resin composites using Er2O3 and WO3 as radiation shielding functional particles and epoxy resin as the matrix. Also, they performed detailed testing and characterization of their microstructure, mechanical properties, and radiation shielding properties.
