Aluminum fluoride and precautions for use

【China Aluminum Network】 colorless or white crystal. Insoluble in water, insoluble in acid and alkali. It is very stable in nature and can be hydrolyzed under heating. Mainly used for aluminum. Aluminum trichloride and hydrofluoric acid, ammonia water system.

Function and use

It is mainly used for aluminum production to reduce the melting point and increase the conductivity of the electrolyte. It is used as an inhibitor of sub-fermentation in alcohol production. Also used as a flux and glaze component of ceramic glazes and enamel glazes. Also used as a flux for smelting non-ferrous metals

Usage Notice Hazard Overview

Health hazards: hydrogen fluoride decomposition products are irritant, can cause eye, respiratory mucosa irritation, severe cases can occur bronchitis, pneumonia, or even produce reflective suffocation.

Explosion hazard: The product is non-flammable, toxic, and irritating, and it seriously damages the mucous membranes, upper respiratory tract, eyes and skin.


Skin contact: Remove contaminated clothing and thoroughly wash skin with soap and water.

Fire-fighting measures

Hazardous characteristics: Can react violently with alkali metals.

Hazardous combustion products: hydrogen fluoride, alumina.

Extinguishing method: Extinguish with plenty of water. Use mist water to disperse smoke and irritating gases.

Emergency response

Emergency treatment: Isolation of contaminated areas and restrictions on access. It is recommended that emergency personnel wear a dust mask (full face mask) and wear protective clothing. Do not touch the spill directly.

A small amount of leakage: Avoid dust, collect with a clean shovel in a dry, clean, covered container.

A large number of leaks: collected and recycled or shipped to waste disposal sites for disposal.

Handling and storage

Handling precautions: Closed operation, local exhaust. Operators must be specially trained to strictly observe the operating procedures. It is recommended that operators wear self-priming filter type dust masks, chemical safety glasses, gas-permeable protective clothing, and latex gloves. Avoid dust. Avoid contact with acids. It should be lightly loaded and unloaded during handling to prevent damage to the packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues.

Storage Notes: Store in a cool, ventilated warehouse. Package sealed. Should be stored separately from acids and food chemicals and avoid mixing. Storage areas should be equipped with suitable materials for containment and leakage.
