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.

In addition to its crystal structure and purity affecting the physicochemical properties of tungsten disulfide (WS₂), impurities such as carbon, hydrogen, and oxygen also influence its properties. Although these impurity elements are present in small amounts, their impact on tungsten disulfide properties is significant. Regarding carbon, it affects the structure, electrical properties, mechanical properties, and chemical stability of WS₂ to a certain extent.

Tungsten disulfide (WS₂) is an inorganic compound composed of tungsten (W) and sulfur (S) elements. In addition to its high tungsten and sulfur content, it also contains trace impurities such as oxygen, carbon, hydrogen, and phosphorus. Among these, the oxygen content in WS₂ primarily originates from impurities in raw materials, the production environment, and the introduction during post-processing.

Tungsten disulfide (WS₂) produced by CTIA GROUP LTD is an important transition metal sulfide with characteristics such as a high melting point, high hardness, excellent wear resistance, and lubricity. It can be used as a lubricant to reduce friction coefficients and wear. In the electronics field, it can be applied in the manufacturing of transistors, sensors, and other devices. In the catalysis field, it can be utilized in certain organic reactions.
