Applications
Pigments and Colorants: Stable artificial inorganic pigments, widely used in the manufacture of paints, inks, plastics, and art pigments, providing bright, deep blues.
Radioactive Cesium Antidote: Used in the medical field to treat radiation poisoning. It binds to toxic ions in the intestines, preventing their absorption and promoting their excretion (as an oral antidote).
Electrochemical Materials: Used as a component in electrochemical sensors and electrochromic materials. Due to its unique redox activity, it is being investigated for use in energy storage devices (such as electrode materials for sodium-ion batteries).
Packing
25kg/fiber drum or multi-layer paper bags (lined with moisture-proof PE inner bags), or 500kg anti-static bulk bags.
Storage
Must be stored in a cool, dry, and well-ventilated dedicated warehouse. Keep away from heat sources and open flames; suggested storage temperatures should not exceed 30°C. Keep containers hermetically sealed and sheltered from ambient moisture. Strictly avoid joint storage or contact with strong alkalis, powerful oxidizers, or mineral acids.
