Are any of these chemicals useful?

[SingularisMalefactor]

I have a number of bags of small crystals, and I've looked up the chemicals and what they're used for, but I haven't found anything on whether they would do anything if mixed with other pyrotechnic chemicals. Here they are:

 

Potassium Aluminum Sulfate, KAl(SO₄)₂

 

Monoammonium Phosphate, NH₄H₂PO₄

 

Potassium Chromium Sulfate, KCr(SO₄)₂

 

I just want to know if these would kill a firework, or what effect they would have on it.

first one nope but makes lovely crystals

second one probably not and dangerous with chlorate's

thrid one makes lovely crystals and is compatible with the top one for making crystals (surprisingly) so you can control the colour (well darkness)

I think the only use you will find is the monoammonium phosphate. It has sparing use as a fireproofing agent, perhaps for parachutes.
