Tungsten Trioxide Electric Property

When current flows through a conductor, the conductor may have a fever, this heat generated by the current, called electric, or it can be understood as electric power is generated by the heat, the phenomenon of electrical energy becomes into internal energy. The use of electric principle can be made into various electric heaters, such as electric irons, electric stove, electric irons, electric ovens, water heaters, electric hatch boxes.

Electric material is a new energy material which has relatively traditional energy with small size, no noise, no pollution, long life and other characteristics. Thermoelectric materials can be used as electricity and thermal energy conversion intermediary material. The material will appear the temperature difference, and this electric conversion is reversible. Conventional thermoelectric materials have high ZT value (figure of merit, the higher the coefficient, the higher thermoelectric conversion efficiency), and the preparation of a mature technology, it has been widely used in thermoelectric power generation and refrigeration device. Some researchers are finding new thermoelectric materials, although these materials have a higher ZT value, it is the most toxic and precious metal alloys division, the use of these materials will increase in the environment.

Tungsten trioxide (WO₃) as important high-tech materials in the electrochromic, the light catalytic degradation, the gas detection and other areas has a wide range of potential applications. WO₃ is an n-type thermoelectric material at the same time. Currently, the status quo is thermoelectric materials research with P-type thermoelectric material, but it is necessary for the production of thermoelectric devices p-type matches with n-type. Early, studies have shown that WO₃ doped thermoelectric performance, which has been improved. If we find a important dopant and it will be the best process parameters for WO₃ thermoelectric properties, it is possible to WO₃ used in thermoelectric materials.
