    This gas was first synthesized in 1900. It is used inside circuit breakers to extinguish the electrical arc when the contacts inside the circuit breaker are pulled apart, thus enabling the electrical circuit to be broken. The gas is also a very good insulant to withstand electrical dielectric stresses.
