The physical properties of this chemical are below: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)Exact Mass: 26.014407; (4)MonoIsotopic Mass: 26.014407; (5)Heavy Atom Count: 2; (6)Complexity: 2; (7)Covalently-Bonded Unit Count: 2.

The production method of this chemical is below: The neutralizational process is often used in industry. This is prepared by the reaction of lithium carbonate or lithium hydroxide and hydrofluoric acid, with the chemical equation Li₂CO₃+2HF=2LiF+CO₂+H₂O. 

As to its usage, it is widely applied in many fields. It could be used as the cosolvent which is widely used in the soldering progress for glass lining, copper and aluminium, and also in salt melting chemical technology; It could also be used as the additives of aluminium electrolysis and rare earth electrolysis; Then it is usually used as the desiccating agent and then in producing the optical glass; In addition, this chemical is even recommended to be as the heating medium of keeping solar radiation thermal energy.

When you are using this chemical, you should be very cautious. For being among the toxic chemicals, it may at low levels cause damage to health. This is irritating to eyes, respiratory system and skin and if by inhalation, in contact with skin and if swallowed, it will be dangerous. Then if contacting with acids, it will liberate very toxic gas. Therefore, you could take the different measures to deal with different cases. Wear suitable protective clothing, gloves and eye/face protection. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice and if in case of accident or if you feel unwell seek medical advice immediately (show the label where possible). Then remember not to breathe dust.

Additionally, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: [Li+].[F-]
(2)InChI: InChI=1S/FH.Li/h1H;/q;+1/p-1
(3)InChIKey: PQXKHYXIUOZZFA-UHFFFAOYSA-M
