ABSTRACT:
A method for forming a high-velocity gas stream stably, which comprises jetting out a gas having an oxygen content of 0 to 2% by volume under pressure from a jet opening having an inside wall made of a platinum-group metal and maintained at a high temperature. This method effectively prevents the consumption of a jet opening made of a platinum-group metal.
