I also want to make a tube furnace (see my other thread about furnaces), but it is a more specialized peice of equipment so I would like to get my
'oven' type furnace ready first, but anyway I am curious:
I see they sell between 2-4 zones, with more available with custom order.
What is the purpose of 'zones' in tube furnaces? Can you give examples of reactions that require zones?
I would like to at least in my head begin to design a nice tube furnace (one that opens up and stuff), but I wanted some kind of reference material
and anecdotes to read about more complicated reactions that require thermal zones.
I have used simple tube furnaces before (heated with flame) for continuous reactions, but anyway...

The first thing that comes to my mind is hydrothermal growth, which requires a hot zone and a room-temperature 'cold' one. Really, any reaction that
relies on 'isolation' or 'distillation' could more or less boil down to that concept. As for multiple hot zones, I'm unsure. Perhaps different
gradients of heat for semiconductor manufacture?

Also what temperature range is good for a tube furnace?
Are there alot of reactions that require temperatures greater then 1200C? It looks like past this point you would need to go to some kind of custom
layed Molybednium Disilicide elements.
