What Is the Tungsten Trioxide Ceramic?


Tungsten trioxide (WO3) is a high-tech material that possesses unique properties such as non-linearity, high dielectric constant, electrochromism, gas detection, and chemical catalysis. In this article, we will discuss tungsten trioxide ceramics - a material made of tungsten and ceramic materials.

Advantages of Tungsten Trioxide Ceramics

Tungsten trioxide ceramics are a type of metal ceramics that exhibits exceptional advantages such as high-temperature resistance, chemical corrosion resistance, good thermal conductivity, and high mechanical strength. It is a material made of rare earth-doped tungsten trioxide and ceramic materials such as clay. By adding tungsten trioxide to ceramics, it becomes resistant to high temperatures and less prone to breaking.

Applications of Tungsten Trioxide Ceramics

Tungsten oxide ceramics have several applications, including:

Photochromic Characteristics: The photochromic properties of tungsten trioxide can be used for high-density storage, image display, laser printing, and switching devices.

Photocatalytic Degradation: Semiconductor tungsten oxide can be used as a photocatalyst to decompose harmful substances in sewage treatment and deep treatment of domestic water.

Piezoresistor: Tungsten trioxide can be used as a pressure-sensitive resistive material in low-pressure pressure-sensitive applications.

Solid Solution Electrode: Alkali-doped tungsten oxide is the most ideal cathode material for batteries, and these cathode materials are sometimes called solid solution electrodes.

Microwave Absorber: Tungsten trioxide has good electromagnetic wave absorbability and can be used in mobile communication and satellite communication.
