Lithium carbonate, an inorganic compound with the chemical formula Li2CO3, is a colorless monoclinic crystal or white powder. The density was 2.11g/cm3. The melting point is 723 ℃ (1.013 * 10 ^ 5pa). Soluble in dilute acid. It is slightly soluble in water and more soluble in cold water than in hot water. Insoluble in alcohol and acetone. It can be used to make ceramics, medicine, catalyst, etc. Commonly used raw materials for lithium ion batteries.

Because the main raw material for producing lithium carbonate is salt lake brine (the ore method has a small production capacity in the world due to its high cost), it is necessary for large-scale enterprises to produce lithium carbonate to have the right to exploit salt lake resources with rich lithium resources, which makes this profession have a high resource barrier; On the other hand, because the vast majority of salt lake resources in the world are high magnesium and low lithium type, and it is very difficult to purify separation lithium carbonate from high magnesium and low lithium old brine. Previously, these skills were only held in the hands of a small number of foreign companies, which makes lithium carbonate profession have a skill barrier. As a result, it has created a global monopoly pattern of lithium carbonate occupation.

At present, the global lithium carbonate market concentration is very high. Before several large-scale projects in China were put into operation, the main global production capacity was concentrated in the hands of sqm, FMC and chemetall; According to the data, although there are certain resource and skill barriers for lithium carbonate products, there are still many salt lakes with Exploitable value in China. In addition to CITIC Guoan and Tibet Mining, salt lake group is also facing a breakthrough. The occupational barriers are gradually weakening, and the current high gross profit rate of the occupation will inevitably attract more capital intervention.

Handling and Storage

Operation precautions: airtight operation, provide sufficient local exhaust. Prevent dust from being released into the air of the workshop. It is necessary for operators to receive special training and strictly abide by the operation regulations. It is suggested that operators should wear dust masks (full face masks), gas permeable gas suits and rubber gloves. Prevent dust generation. Prevent contact with oxidants, acids and fluorine. Equipment leakage emergency treatment equipment. The empty container may contain harmful substances.

Storage precautions: store in cool and ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The package is sealed. It should be separated from oxidants, acids and fluorine, and should not be mixed. The storage area should be provided with appropriate data to contain leakage.
