calcium chlorate


Can calcium chlorate be prepared the same way as sodium chlorate(electrolysis)? It has a better oxygen content than potassium chlorate, but i don't know if it can be prepared that way. Also, i don't know if this salt is hygroscopic, or safe to use in pyrotechnics. Any information about this salt will be appreciated.

Calcium chlorate is deliquescent, making it very awkward for use in pyrotechnics . . .

I'm no pyroguy but a birdie told me chlorates are generally 'out' for pyrotechnics (flash powder/shock sensitivity of chlorate containing pyromixes) and that perchlorate is much preferred for that reason.

Check out dann2's site here;

http://www.oxidizing.110mb.com/chlorate/calcium.html

The main problem (apparently) is the build-up of Ca(OH)2 (lime) on the cathode.

Wouldn't it also contaminate the flame color as well?

For pyro mixtures potassium chlorate is your best option (it has really weak emissions and is very easy to color). woelen's site also has some stuff with cesium chlorate.




At the end of the day, simulating atoms doesn't beat working with the real things...
