Nano tungsten oxide, which may be applied for producing heat insulation coating, is an n-type semiconductor material and a “d0” oxide. Such two features make tungsten oxide have many advantages at the same time. Although tungsten oxide is often present in various structures such as amorphous structure, monoclinic structure, and hexagonal structure, while its main structure is composed of tungsten-oxygen octahedron connected end to end. Depending on the crystal structures and surrounding environment, the octahedral unit will be distorted in…

Nano tungsten oxide may be used to produce thermal insulation coating with excellent photochromic properties. Tungsten oxide is also a type of electrochromic material. It is worth noting that the reversible transformation process of tungsten oxide and tungsten bronze is always accompanied by the transfer of internal electrons and the change of tungsten valence, which will induce a color change reaction and achieve controllable adjustment of transmitted light. This feature was first discovered in 1969 and has since been widely…

Nano tungsten oxide may be used for the preparation of near-infrared shielding material, which plays the role of “heat insulation, energy saving and anti-glare”, mainly reflecting its photochromic properties. As a new dingal material, tungsten oxide has many excellent characteristics such as easy synthesis, low energy consumption, wide viewing angle, long working life, good stability, high coloring efficiency, low production cost, and strong color contrast, etc. Such advantages make tungsten oxide become one of the research hotspots in the field…

Nano tungsten oxide may be used for the preparation of nano-ceramic dispersion solution. Tungsten oxide can also be used in smart windows, which mainly reflects its electrochromic properties. And such smart windows are mainly to meet different requirements of people for room temperature and daylighting in different seasons and different time periods as the heat insulation performance of tungsten oxide is excellent with high visible light transmittance. The heat insulating film of tungsten oxide has become a hot spot in…

Nano tungsten oxide may be applied for preparing thermal insulation film. This kind of heat insulation film is a type of excellent building energy-saving material, which can be applied in various architectural glasses. Due to environmental protection, energy conservation and rising energy prices, transparent heat insulation film of tungsten oxide has received more and more attention at home and abroad. Therefore, the problem of energy consumption control in building heating and cooling has also arisen. Among them, the energy loss…

Nano tungsten oxide has excellent thermal insulation properties so that it may be applied for manufacturing thermal insulation paper. Tungsten oxide may also be applied in architectural glass to reduce building energy consumption. According to relevant data, more than 86% of the existing 43 billion square meters of buildings in China still use ordinary single-layer glass, which has poor thermal insulation performance. Faced with the urgent demand for low energy consumption in buildings in the current market, various energy-saving glasses…

Nano tungsten oxide may be applied for producing thermal insulation masterbatch, which reflects its photochromic properties. Tungsten oxide also has electrochromic properties so that it can be used for heat insulation in large-area building curtain walls, such as, architectural glass. Among them, the two most important performance indicators of solid inorganic electrochromic materials in large-area building curtain wall applications are — response time and cycle life. Then, there is something about the research progress of the electrochromic properties of tungsten…

Nano tungsten oxide may be used for the preparation of nano-ceramic color master. Tungsten oxide also has photocatalytic properties so that it can be used for photocatalytic degradation of organic contaminants, such as organic dyes, more specifically, photocatalytic degradation of triarylmethane. Triarylmethane has been widely used in printing and dyeing, optical reagents, nonlinear optical materials and other fields. However, some triarylmethane dyes have certain toxicity, which is manifested as carcinogenic, toxic to aquatic organisms and irritating to the eyes. Rhodamine…

Tungsten oxide may be applied for the preparation of ceramic microsphere. Tungsten oxide powder can also be applied in the photocatalytic degradation process of organic dyes. As you may have known, the application of organic dyes can be seen almost everywhere in our lives. They bring more colors to our world. However, these dyes actually have certain dangers, such as anthraquinone pigments. Anthraquinone pigments, which are characterized by bright colors and high solid color, are widely used in the printing…

Tungsten oxide may be used in heat insulating window glass, which mainly reflects its photochromic properties. Tungsten oxide powder may also be used for photocatalytic degradation of organic dyes (contaminants). Dye, as a substance that brings us color, is almost used in all aspects of life. For example, azo dyes, which have the advantages of low synthesis cost and outstanding dyeing properties, are widely used in the dyeing of fibers, leather, wood, plastics, rubber, and food, etc. And they are…
