If powder aluminium + Phosphorus + Sulphur were mixed together and heated what would be the resulting compound? Would it be AlP + S


Thanks for any help

if you would heat them in inert atmosphere (Argon for example) I would expect phospherous sulfides, P_xS_y (sorry no idea what the coefficients may be) Aluminium Sulfide Al₂S₃ and aluminium phosphide AlP to be possible products.

if you heat them in air, all would form oxides.

I guess this would be quite a nasty mix, dangerous/harmful to preform?

yes.

aside from tricky as you don't want to expose it to air or water (the sulfide/phosphide compounds will hydrolize easily) they will form for example toxic H₂S when exposed to water
Aluminum phosphide is a pesticide, and thus toxic.

Better not to perform any of this unless you know what you are doing, and doing it properly and safely.
