Oxidizer purities

I got an offer talking about 99,3% pure KClO3 and KClO4, a lot cheaper than purer material. Are both practically useable?
Until which percentage is "technical grade" practically allowed?
Thanks

I know what you mean, but even skylighter doesnīt list these. I donīt know any source that lists it. No idea what the rest contains.
I suppose the one to watch out for on the perc is chlorate contamination, easy enough to test for. Other than that 99.3% pure should be more than good enough as far as I am aware.
The one that I have found that makes a big difference regarding purity is Strontium Nitrate (I know that was not strictly the question asked), I have a few grades and the less pure one seems to be far more hygroscopic for whatever reason (maybe calcium nitrate contamination?).

Interesting fact about Sr(NO3)2: maybe it also contains some sodium salts...

hey guys, as the very safe and cautious individual i am, i recently decided to make my own kclo4, ( impossible to obtain where i live ) i did hours upon hours of cross reference research before my attempt. I have a 2lt perc cell with a pt anode and ti cath' and have produced about 2Lb of what i thought was k perc, concidering as i was harvesting my yield i was boiling it in hcl for about 30 min then bumping up the ph with NaOH then filtering. My fist test was with dark indian blackhead Al, 70 ; 30 and had magnificent results far above my dreams and expectations, ''But'' then i did a rudimentary test of my kclo4, with sucrose and con h2so4 and was horrified to see it burst into life with brilliant purple flames confirming to me i had a unknown % of kclo3, indigo carmen is unavailable to me and methylene blue indicates perchlorate present, my delemer is either boiling in hcl don't work or i did it wrong, i now use this stuff as kclo3 but would prefer kclo4, any suggestions on purification would be greatly appreciated, regards phill
I can't really help you with this one, BUT, there is a whole thread devoted to perchlorate synthesis "right here" in the chemistry section. Take a look through there and maybe you'll find some info.

I honestly think that chlorate, or metal salt, contamination is what made some of the "best" perchlorates so reactive. I've used reasonably pure perchlorates, but the swedish material is still some of the strongest I've ever used.
