Inert gas as a cover

Post by mite5255 »

If using an inert gas as a cover, do you just squirt the gas into the crucible, plus as it heats up does the gas rise out of the crucible

A lot would probably depend on how much turbulence you have inside the furnace. An electric wouldn't have much but a forced air gas burner would blow all the gas out the top. A small tube feeding the gas in at a slow rate would help, but then you have to worry about the tube melting.

Thanks Jammer, I was going to try just for an experiment to see how well it would work
