Lithium Carbonate
Main content: 99.2%~99.7%
Lithium carbonate is an important lithium compound with wide applications in numerous fields. It is composed of lithium (Li), carbon (C), and oxygen (O), and its chemical formula is Li2CO3. With the development of technology and the progress of industry, the importance of lithium carbonate has become increasingly prominent.
I. Basic Information
- CAS Registry Number: 554 - 13 - 2
- EINECS Registry Number: 209 - 052 - 0
II. Physical and Chemical Properties
- Appearance: White monoclinic crystals or powder, odorless.
- Melting Point: 723°C (It begins to partially decompose into lithium oxide and carbon dioxide at around 850°C).
- Density: 2.11 g/cm³
- Solubility: Slightly soluble in water, and its solubility in cold water is slightly higher than that in hot water; insoluble in alcohol and acetone, but soluble in dilute acids.
III. Preparation Methods
- Ore Extraction Method: Lithium ores such as spodumene are crushed and ground, then undergo roasting reactions with sulfuric acid, etc. After a series of processes such as leaching, impurity removal, and precipitation, lithium carbonate products are finally obtained. This method is one of the commonly used methods in current industrial production and is suitable for areas rich in lithium ore resources.
- Salt Lake Brine Extraction Method: To extract lithium carbonate from salt lake brine, the brine needs to be pre - treated for magnesium and boron removal first. Then, through steps such as evaporation concentration and adding precipitants, lithium precipitates in the form of lithium carbonate. Due to the rich lithium resources in salt lake brine, this method has developed rapidly in recent years and has the advantages of low cost and high resource utilization rate.
IV. Application Fields
- Battery Industry: Lithium carbonate is a key raw material for preparing cathode materials of lithium - ion batteries and is widely used in various lithium - ion batteries such as those in mobile phones, laptops, and electric vehicles. With the rapid development of the new energy vehicle industry, the demand for lithium carbonate is also growing rapidly.
- Glass and Ceramic Industry: Adding lithium carbonate in glass manufacturing can reduce the melting temperature of glass and improve the transparency and strength of glass; in ceramic production, lithium carbonate can improve the sintering performance of ceramics and enhance the quality and performance of ceramics.
- Pharmaceutical Industry: In the pharmaceutical field, lithium carbonate is mainly used to treat mental illnesses such as mania. It can regulate the function of the human nervous system, stabilize emotions, and has a significant effect on treating mental illnesses.
- Metallurgical Industry: In the metallurgical process, lithium carbonate can be used as a flux to lower the melting point of metals and improve the extraction efficiency and purity of metals.
V. Precautions
- Health Hazards: Lithium carbonate is toxic to the human body. Excessive intake may cause symptoms such as dizziness, vomiting, and diarrhea. In severe cases, it can affect the nervous system and cardiovascular system. During use and storage, avoid inhaling dust and accidental ingestion.
- Environmental Impact: Lithium carbonate may cause certain pollution to water bodies and soil in the environment. Therefore, during production and use, its emissions need to be strictly controlled, and the treatment and recycling of waste should be well - done.
- Storage Requirements: It should be stored in a cool and ventilated warehouse, away from ignition sources and heat sources. Prevent direct sunlight, and the packaging must be sealed to avoid moisture.
