Boron trifluoride BF3 Gas

Product nameBoron trifluoride BF3 Gas



Dot Class:2.2

Other Names:Trifluoroborane

CAS NO:7637-07-2

Grade Standard:Electron Grade, Industrial Grade


Boron trifluoride (BF3) is a colorless gas with a strong smell at room temperature. It does not burn or support combustion. It is 1.3 times heavier than air and produces white smoke when mixed with wet air, with a purity higher than 99.6%. Boron trifluoride can corrode glass at room temperature, while wet boron trifluoride is very corrosive. BF3 is used as a catalyst in organic synthesis, as a raw material for the synthesis of organic borides, and also used in nuclear technology and optical fiber. In the electronics industry, it is mainly used as p-type dopant, ionization particle into the source and plasma energy etching gas. BF3 and compound are used as curing agents in epoxy resins. It is also used as a lubricant in cast steel.

Boron trifluoride (BF3) is toxic. The main symptoms of acute poisoning are dry cough, shortness of breath, chest tightness, chest urgency; Some patients have nausea, anorexia, salivation; When inhaled, tremors and convulsions may occur, which may also cause pneumonia. Burns may occur on skin contact. Bottled gas products are high pressure filled gas, which can be used after decompression and depressurization. There is an expiry date on the packaged gas cylinders. The expired gas cylinders must be sent to the relevant departments for safety inspection before they can be used. When each bottle of gas is used to exhaust gas, the residual pressure in the bottle should be kept at 0.5mpa, and the minimum residual pressure should not be less than 0.25mpa. The bottle valve should be closed to ensure the quality and safety of gas. Bottled gas products should be piled up in categories during transportation, storage and use. Combustible gas and combustion-supporting gas are strictly prohibited to be stacked together, and are not allowed to be near open fire and heat source. They should be kept away from fire, oil and wax, sun explosion, heavy casting and impact
