What is the nature by which basic alkali chlorate/reducer admixtures, are more shock sensitive than CLO4? Does the final oxygen occupy a space, and
reduce strain?

KClO4 with sugar doesn't burn fast at all. With charcoal and sulfur I think it's slower then black powder.

Interesting, I would have guessed that the extra AVAILABLE oxygen (unlike limited availability on NO3-), would have increased all aspects of the
oxidizer's brasiance.
Still, have no real experience with perchlorate. Chlorate was my thing. I remember the old Bernz-O-Matic oxygen sticks...too young for the weed
killer 
Still old enough to remember Benzene being sold in gallon tins just like
toluene though. Like to find one of them half full at an old garage sale. mua haha

If you do come across benzene, treat it like the dangerously toxic carcinogen it is!

RIGHT, hissingnoise, and all other chemicals are benign/non mutagenic. Why wouldn't you treat specific reagents appropriately and carefully? It
would make no sense to not do so. But THANK YOU for the reminder ;-))

It's likely partly a matter of perchlorate allowing the central chlorine to achieve a noble gas electron structure.

thank you Mumbles.

Look up the melting temperature of potassium chlorate vs. the perchlorate. Note that most pyrotechnic systems ignite at the melting point of one of
their ingredients... Solid-solid reactions are generaly slow goers due to limited contact between grains of the reactants. Get one reactant liquid or
gaseous and the other reactants immersed in it, things pick up speed due to increased surface area of reaction.
Note that the disassociation of potassium chlorate actually YIELDS a small ammount of energy, rather than TAKING a substantial bit of energy as the
perchlorate does.
Draw conclusions on why the Chlorate mixtures have a reputation for sensitivity...

Having in mind how powerful ethyl perchlorate is, I was wondering if it's possible to vacuum distill HClO4 and mix with fuel to make very strong
explosive. According to wikipedia perchloric acid has density near 1.7.

The history of accidents and explosions related to people working with high percentage chloric and perchloric acid would stop me from ever trying
that. Check the literature.
Pure perchloric acid doesn't need a fuel, it explodes all by itself. There's a good reason that 70% is the highest purity that will be shipped.
Industrial fume handling equipment in perchloric acid areas have been known to just blow up from the contamination they build up in use.
Mixing perchloric acid with an organic fuel usually results in a fire or explosion... and organic perchlorates are way up on my list of things to
avoid making or handling. The videos of the behavior of ethyl perchlorate should scare the hell out of you and keep you from making more than a few
drops even with good safety equipment. It's odd to say this, but you're much safer handling a relatively benign chemical like nitroglycerin.

There's good reason why they don't ship ap also 
Who would've guessed that a
primary like EtClO4 would be more powerful then the newest ddf, cl-20 and hexanitrocubane.
