Product Functions
- Optical Transmission: Excellent transmission in the infrared (IR) spectrum, ideal for lenses, windows, and optical coatings.
- Luminescence: Acts as a phosphor in electroluminescent displays, LEDs, and glow-in-the-dark materials.
- Pigmentation: Used as a white pigment in plastics, ceramics, and paints due to its high opacity and stability.
- Catalysis: Serves as a catalyst in certain chemical reactions, including hydrocarbon processing.
- Semiconductor Properties: Applied in photovoltaic devices, sensors, and thin-film electronics.
- UV Absorption: Provides UV-blocking capabilities in coatings and composites.
Application Areas
- Optics & Infrared Systems: Windows, lenses, and domes for thermal imaging, missile guidance, and night-vision equipment.
- Electronics: Phosphors in cathode ray tubes (CRTs), X-ray screens, and electroluminescent panels.
- Paints & Coatings: Anti-corrosive and UV-resistant coatings for automotive, aerospace, and marine industries.
- Plastics & Ceramics: Additive for improving whiteness, strength, and thermal stability.
- Security & Printing: Used in security inks, fluorescent markers, and anti-counterfeiting technologies.
