What are the properties of tungsten dioxide?
Tungstenoxid A light yellow triclinic powder, its chemical formula is WO3. If the temperature rises above 740°C, the tungsten oxide becomes orange tetragonal crystals. These return to their original states after cooling. With a melting point at 1473°C, an boiling point greater than 1750°C, as well as a relative density of 7.16, tungsten oxide powder is very stable in air.
Inorganic acids and water are insoluble in tungsten oxide. To make soluble tungstate from WO3 powder, you can dissolve it in hot concentrated sodium hydroxyide solution. If the temperature exceeds 650 degrees, it can be reduced with H2 and reduced further by C. To obtain tungsten-powder at 1000-1100 degrees Celsius
Which tungsten-oxide application is it?
Everyday life has many uses for tungsten oxide. This is used for making tungstate, as well as in industrial X-ray screening phosphors. Its rich yellow pigments make tungsten oxide a popular choice for paints, ceramics, and other applications.
The production of electrochromic and smart windows has used tungsten oxide. These windows have the glass of an electric switch. They also show the light transmission and voltage changes. It allows you to tint your windows with changes in heat or light. High-density explosives made of inert metals are another option. This is especially true in the conflict between Israel (2008) and Gaza 2009 (2008-2009).
Some tungsten dioxide is used for chemical products like paints and coatings and petroleum industry catalysts. But tungsten oxide can be used as an intermediate product. It is used in metal-tungsten powder and in tungsten carbide powder. This is followed by the mass production and application of tungsten alloys. These include tungsten copper and tungsten nickel.
