Yellow tungsten oxide (WO₃), produced by CTIA GROUP LTD, is a chemically distinctive compound. It appears as a fine yellow powder, insoluble in water yet soluble in alkaline solutions, with limited solubility in acids. Composed of one tungsten atom (W) bonded with three oxygen atoms (O), this atomic arrangement endows WO₃ with unique physical and chemical properties.

Yellow tungsten oxide (WO₃), produced by CTIA GROUP LTD, is a crucial oxide of tungsten. Visually, it appears as a fine, yellow crystalline powder. At room temperature, WO₃ exhibits stable properties, making it relatively safe for storage and transportation without requiring special environmental conditions to maintain its chemical structure. With a density of approximately 7.16 g/cm³, a melting point as high as 1473°C, and a boiling point exceeding 1750°C, its ability to remain solid under high temperatures lays the foundation for its applications in high-temperature industrial settings. Additionally, WO₃ is insoluble in water and inorganic acids (except hydrofluoric acid) but dissolves in alkaline solutions such as ammonia. This unique solubility determines its reactivity and application potential in various chemical environments.

Tungsten disulfide (WS₂) is an inorganic compound composed of tungsten (W) and sulfur (S) elements.
