Note: If the buyer has special requirements, it shall be negotiated by the supplier and the buyer. Function and use: Industrial grade lithium carbonate is mainly used in steel continuous casting mold powder; in the electrolytic aluminum industry, adding industrial grade lithium carbonate can reduce the volatility, viscosity and melting point of the electrolyte, improve the conductivity of the electrolyte, thereby reducing heat loss and increasing Current efficiency, energy saving and prolonging the service life of the electrolysis cell; used to prepare the refrigerant lithium bromide; used to prepare the raw material for lithium metal electrolysis; lithium chloride; used to prepare the raw material for high-purity lithium carbonate and pharmaceutical grade lithium carbonate; Used in glass, ceramics, enamel and enamel, etc. Storage and use: The powder should avoid contact with eyes, skin and clothes; keep it away from strong acids and strong oxidizing substances, and store it in a dry and airtight manner. Packing: paper-plastic composite bag lined with 2 layers of PE bag, 25 kg/bag or according to customer requirements. Transportation: The product is not classified as a hazardous chemical and is suitable for shipping, railway, air and road transportation. Pay attention to moisture and acid prevention during transportation. |
