Beryllium Fluoride With Strong Irritation
Beryllium fluoride is a chemical substance, white powder or crystal, melting point 552 ℃, boiling point 1175 ℃, relative density (water = 1): 1.9860. It is harmful to the environment, the water can cause pollution. This product is noncombustible, toxic, for carcinogens, with strong irritation.
Beryllium or beryllium hydroxide dissolved in 25% NH4HF2, in platinum or lead containers can be concentrated in the ammonium tetrafluoroborate (NH4) 2BeF4 crystal, and then heated to 450 ℃ in the carbon dioxide stream can be pure BeF2 , Can also be used beryllium carbonate and hydrogen fluoride gas reaction in the presence of water will only be able to get the basic salt 5BeF2 · 2BeO.
Handling and storage
Handling Precautions: Closed operation, providing adequate 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 advisable for the operator to wear a dust mask (full cover), wear a rubber stopper, and wear rubber gloves. Avoid dust. Avoid contact with 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 stored separately with acids, edible chemicals, avoid mixed storage. The storage area should be equipped with suitable materials to contain spills.
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 amount of leakage: carefully swept away, collected in a closed container.
A large number of leaks: collected or transported to the disposal of waste disposal sites.
