Application Fields
- Industrial and Daily Use:
- Used in X-ray screen phosphors and flame-retardant fabrics for producing tungstates.
- Utilized as a pigment in ceramics and paints due to its rich yellow hue.
- Smart Glass Production:
- Employed in electrochromic windows (smart windows) where glass transparency adjusts with applied voltage, allowing users to modulate heat or light.
- Chemical Product Manufacturing:
- Applied in paints, coatings, and as catalysts in the petroleum industry.
- As an intermediate product, tungsten oxide is extensively used to produce tungsten metal powder and tungsten carbide powder for manufacturing tungsten alloys like tungsten-copper, tungsten-nickel, and various hard alloys.
- Advanced Applications:
- Used in solar energy absorption materials, stealth materials, and semiconductors with excellent gas sensitivity.
- Serves as a catalyst with unique catalytic properties and as a colorant for ceramics.
- Also used in the production of ultrafine tungsten powders and fire-resistant materials.
Packaging and Storage
- Packaging: Sealed in aluminum foil bags.
- Storage: Store in a cool, dry environment, avoiding long-term exposure to air to prevent moisture absorption and agglomeration, which could affect dispersibility and performance.
