LITHIUM BORATE, META - Introduction
Lithium metaborate dihydrate, chemical formula LiBO2 • 2H2O, is an inorganic compound. It is a white crystalline solid, soluble in water at room temperature. Its nature is as follows:
1. Thermal stability: Lithium metabolate dihydrate is relatively stable at temperatures below 200 ℃, but can be decomposed at high temperatures.
2. Water solubility: The compound is soluble in water and slightly soluble in water, and the solution is alkaline.
3. Acid and alkali: Lithium metal borate dihydrate can be hydrolyzed to produce metaborate ion (BO2-), so it can be regarded as an alkaline compound.
4. Use: it is widely used in batteries, ceramics, coatings and other fields. In batteries, it is often used as a positive electrode additive for lithium-ion batteries; In ceramics, it can be used to increase the hardness and wear resistance of ceramics; In coatings, it can enhance the fire resistance of coatings.
5. Preparation method: Lithium metal borate dihydrate can be prepared by dissolving Lithium carbonate in a small amount of boric acid solution and then evaporating the solvent or crystallizing.
6. Safety information: Lithium metaborate dihydrate is generally safe under normal use conditions, but it still needs to comply with general laboratory operating regulations. During the operation, direct contact with skin and eyes should be avoided. If eaten by mistake, seek medical attention immediately. In addition, Lithium metal aborate dihydrate should be stored in a dry, well-ventilated place, away from fire and oxidizing agents.
