In the human journey of exploring illumination, tungsten filament, as one of the core materials in lighting technology, has played a crucial role. From the initial incandescent bulbs to modern high-efficiency tungsten-halogen lamps, tungsten filament, with its unique physical and chemical properties, has led multiple innovations in lighting technology, bringing unprecedented convenience and comfort to people's lives.

Tungsten disulfide nanosheet is a typical transition metal sulfide. It is a black powder with a chemical formula of WS₂ and a molecular weight of 247.97. It has the characteristics of low friction coefficient, good thermochemical stability and photoelectric properties. It is widely used in lubricants, catalysts, energy storage electrode materials and other fields.

Tungsten wire, as an important industrial material, is widely used in lighting, electronics, medical, aerospace, and other fields due to its unique physical and chemical properties. The following are the main characteristics of tungsten wire, comprehensively demonstrating its advantages in various high-demand scenarios.

Tungsten oxide, as the core "secret weapon" of smart windows, is like a bright star in the field of materials science, shining with a unique light. Its chemical formula is WO₃-x, which is a compound formed by the close combination of tungsten and oxygen. Its appearance presents a variety of colors, the most common of which are light yellow, yellow, orange-yellow, blue and purple, as if it was given a unique color code by nature.
