From chlorate to perchlorate by heating

dangerous amateur - 13-11-2013 at 02:14

Hi,

I managed to get my little chlorate cell to run nicely, but there are many things in field of pyrotechnics that cannot be done safely with chlorates.


Before I start with leadoxide or platinium stuff:
Have you ever considered to convert chlorates to perchlorates just by heating them for some time?

For example sodium perchlorate:
I will end up with a mixture from maybe some leftover chlorate, wich can be destroyed easily.
The perchlorate is much more soluble than the chloride, so I can decant the chloride.
Perchlorate solution is treated with KCl.

Is this useful in practice?

What temperatures are needed and is it possible to get useful yields?
