Lithium carbonate chemical formula Li2CO3, reagent grade lithium carbonate is a high purity lithium carbonate that is widely used in scientific research and industrial applications. It has the following characteristics:
High purity: Reagent grade lithium carbonate has a very high purity, which makes it particularly important in areas where high precision and quality materials are required.
Stability: It shows a high degree of stability under certain conditions, which is conducive to keeping its properties unchanged during various chemical reactions and processes.
Solubility: Although lithium carbonate is slightly soluble in water, its solubility characteristics in certain solvents give it a particular advantage in certain applications.
Reagent grade lithium carbonate is used in a wide variety of applications, including but not limited to:
Pharmaceuticals: It is used in mania, depression, schizophrenia and other drugs.
Industrial applications: used as an important raw material in glass, ceramics, food and other industries. In addition, it can also be used in synthetic rubber, dyes, semiconductors and military defense industry.
In terms of physical properties, reagent grade lithium carbonate usually appears as a white solid, has a relative density of 2.11, melting point of 723 ° C, below 600 ° C is heat-stable, but at 618 ° C began to partially decompose into lithium oxide and carbon dioxide.
Reagent grade lithium carbonate can be produced by a variety of methods, such as precipitation, comprehensive utilization of brine and lime sintering method. Each of these methods has its own characteristics, and a suitable preparation method can be selected according to different raw materials and needs.
The preservation of reagent grade lithium carbonate requires special attention to its stability and purity, and it is recommended to store it in a dry, well-ventilated place without direct sunlight, and use dry, clean and well-sealed containers for storage in order to prevent moisture and impurities from entering. At the same time, it should be ensured that the storage environment is at a suitable temperature, usually between 20° and 25°C, with between 15° and 30°C allowed for short trips. In addition, contact with acids, alkalis and redox substances should be avoided to prevent chemical reactions leading to product deterioration. The stored lithium carbonate should be inspected regularly for caking, discoloration, odor and other phenomena.
