What are the main uses of lithium carbonate?
Lithium carbonates is an inorganic compound with the chemical formula Li2CO3. It is a colorless monoclinic crystal or white powder. It has no deliquescence and is stable in the air. It is thermally stable below 600°C and begins to decompose at 618°C. It forms lithium oxide and carbon dioxide, with a density of 2.11g/cm3 and a melting point of 618°C. It is soluble in dilute acid solution. Lithium carbonates battery grade has a negative temperature coefficient. Its solubility in water decreases as the water temperature increases. Its Solubility is less than other alkali metal carbonates. It does not form double salts with Na2CO3 and K2CO3, so it is easy to separate from other salts and precipitate in a purer form. Insoluble in alcohol and acetone. High-purity lithium carbonate can be obtained by heating the lithium carbonate slurry and then cooling, crystallizing, precipitating and refining.

Lithium hydroxide market operation situation
The hydroxide lithium market is operating weakly and the trading atmosphere is tightening. In terms of raw materials, lithium salt plants are not very receptive to low prices. The transactions are mainly long-term orders, and the price focus of bulk orders has further shifted downwards. With long-term orders sufficient to cover most of the demand for raw materials, downstream procurement has further retreated, with a strong wait-and-see mood; production companies in the downstream lithium salt market have gradually resumed operations, but purchasers are more cautious in receiving goods, and the overall market transaction atmosphere is light. In terms of demand, downstream demand for high-nickel materials is weak, shipments are average, market transactions are dominated by long-term contract orders, bulk transactions are bleak, and the lithium hydroxide monohydrate market continues to remain weak.

Liquid phase method for morpholine
Morpholine is an important organic solvent with polarity and high boiling point characteristics. It is widely used in chemical industry, pharmaceutical and other fields. However, morpholine contains two functional groups (ether group and amine group) in its structure, which makes its analysis somewhat complicated.

Why is hydrazinium hydroxide solution added to boiler feed water?
In order to prevent the boiler water system and pipelines from being corroded by oxygen, and to ensure the complete elimination of residual dissolved oxygen after thermal deaeration and oxygen leaking into the feed water due to loose pumps and water supply systems, it is necessary to add an appropriate amount of combined oxygen to the feed water. ammonia. Hydrazine (N2H4) is also called hydrazine, and its hydrate is commonly used, hydrazine hydrate (N2H4·H2O).
