Does anyone know how hard it is to prepare barium oxide from barium carbonate? Will heating barium carbonate over a propane flame in a crucible for a
few minutes do the job, or are higher temperatures/extended heating required?CobaltChloride - 19-7-2018 at 03:59
According to this it decomposes at 1450 °C which is about the maximum temperature a propane torch can achieve if you put something in the flame: http://chemister.ru/Database/properties-en.php?dbid=1&id... . I doubt it can heat something in a crucible that high
All barium salts decompose at very high temperatures to barium oxide with the exception of Ba(NO3)2 which decomposes at 592 degrees celsius. I think
it would be much better to first react the barium carbonate with nitric acid and heat this mix until it stops releasing NO2.

It's very easy, you just dissolve in dilute acetic acid, then basify with NaOH...JJay - 19-7-2018 at 08:55
