Lithium Fluoride Summary Of Hazards
Lithium fluoride, is a salt, chemical formula: LiF, is the alkali metal halide, white crystals at room temperature, insoluble in water. Used for nuclear industry, enamel industry, optical glass manufacturing, desiccant, flux and so on. It can be lithium carbonate or lithium hydroxide and hydrofluoric acid in the lead or platinum in the crystal in the system.
Role and use
In the ceramic industry, used to reduce the kiln temperature and improve the thermal shock resistance, abrasion and acid corrosion. With other fluorides, chlorides and borates together for metal welding flux. Is the basic component of the electrolytic electrolyte. In the high-temperature battery in the molten state as the electrolyte component. In the proliferation of the reactor as a carrier. A large number of fluxes and fluxes for aluminum and magnesium alloys are also used as additives in the electrolytic aluminum industry to improve the efficiency of electricity; used as a neutron shielding material in the atomic energy industry, as a solvent in a molten salt reactor; Transparent window for UV (transmittance 77-88%).
Summary of hazards
Health hazards: Inhalation, ingestion or percutaneous absorption can be poisoned. Irritating. Large doses can cause dizziness, collapse. Damage to the kidneys. Excessive contact causes increased salivary secretion, nausea, vomiting, abdominal pain, fever, difficulty breathing and so on.
Environmental hazards: harmful to the environment, the water can cause pollution.
Explosion hazard: The product is nonflammable, toxic, irritating.
Skin contact: Immediately remove contaminated clothing, rinse with plenty of water. Medical treatment.
Eye contact: lift the eyelid, rinse with running water or saline. Medical treatment.
Inhalation: quickly from the scene to the fresh air. Keep the airway open. If breathing is difficult, give oxygen. Such as breathing to stop, immediately artificial respiration. Medical treatment.
Ingestion: drink plenty of warm water, vomiting. Medical treatment.
Hazardous characteristics: acid decomposition, the release of corrosive hydrogen fluoride gas. Case of high heat decomposition of highly toxic flue gas.
Hazardous combustion products: hydrogen fluoride, lithium oxide.
Fire fighting methods: firefighters must wear full fire and anti-virus clothing, in the wind to the fire. When the fire is extinguished, the container is moved from the fire to the open. And then according to the reasons for the fire to choose the appropriate fire extinguishing agent fire.
Leakage emergency treatment
Emergency treatment: isolation of contaminated areas, restricted access. Recommended emergency personnel wearing dust masks, wearing protective clothing. Do not touch the spill directly.
Small leaks: avoid dust, carefully sweep, transfer to a safe place.
A large number of leaks: collected or transported to the disposal of waste disposal sites.
Handling and storage
Operation Notes: closed operation, local exhaust. To prevent dust from being released into the air in the shop floor. Operators must be specially trained to strictly observe the operating procedures. It is recommended that the operator wear a self-priming filter dust mask, wear chemical safety glasses, wear toxics, and wear rubber gloves. Avoid dust. Avoid contact with oxidants and acids. Equipped with a leak emergency treatment equipment. Empty containers may be harmful residues.
Storage Precautions: Store in a cool, ventilated warehouse. Away from fire, heat. To prevent direct sunlight. Packaging sealed. Should be with the oxidants, acids, edible chemicals stored separately, avoid mixed storage. The storage area should be equipped with suitable materials to contain spills.
