And while flawed material resulting from problems during graphite production may be the first explanation when someone notices deteriorating graphite materials in their vacuum furnaces, what we have learned through investigation is that simple fixes to the vacuum seal of a furnace can save the graphite, and the furnace’s owner, much grief. Let...
