Application Scope
High purity lithium carbonate is mainly used in the preparation of high-end lithium-ion battery cathode materials and the preparation of battery-grade lithium fluoride; in optoelectronic information, high-purity grade lithium carbonate is used in the preparation of lithium tantalate and lithium niobate; at the same time, high-purity grade lithium carbonate is also used in optical special glass, magnetic materials industry and super capacitors, pharmaceutical industry, etc.
Storage and use: avoid contact with eyes, skin and clothes; keep away from strong acids and strong oxidizing substances, ventilate and store in a dry and airtight place.
Package: High purity lithium carbonate is packed in plastic film bag with inner liner and plastic woven bag with double layer or plastic laminated bag. The inner bag is taped or heat-sealed, and the outer bag is firmly sewn, with a net weight of 25Kg per bag, or as agreed by the supplier and the buyer.
Transportation: The products are not classified as dangerous chemicals and are suitable for sea, rail, air and road transportation. Pay attention to moisture and acid-proof during transportation.
