Take the tour ×  How can I make a single crystal silicon wafer?
What are the tools needed? What is the most diffcult part? Can I
make it at home or at school lab?  I am now interested on
Czochralski process where you melt silicon and let it
crystallize and cut afterwords.  share|improve this question add

anyone. It is possible, but I have to admit - hard. Otherwise,
how were first mono-crystals grown?  Initially, you may buy
'pure' silicon (pure for chemical reactions, not electronics).
First of all you need to make a rod. To do that you'll need form
out of material which can withstand 1600C (hard part, can't name
ones at the moment), and heat Si in it using induction heating.
Induction heating might be the hardest part - but there are lots
of guides around. Induction heater able to melt metal is 100%
doable at home.  Once you have Si rod - you need to purify it
using 'zone melting' using your induction heater. Will take
ages, so you might want t
