Does boron sulphate exist as a compound, just cant find much info on it?
Secondly if I heated elemental sulphur with boron trioxide would I get elemental boron and sulphur dioxide or boron sulphate?
additionally boric acid powder with elemental sulphur?

Boron doesn't form any salts, at least not with any 'B<sup>3+</sup>' cations. So no 'boron sulphate'.

Yeah, the sulfate ion, is of course ionic. Boron, being a non-metal, can only form ionic compounds if it's the anion, not the cation.

Well, it's possible that you *could* make boron sulphate, it just wouldn't be an ionic compound.
I seem to recall reading something along those lines...let's see....Cotton & Wilkinson, 4th Ed, Advanced Inorganic Chemistry notes the existence
of B(HSO4)3 and B(HSO4)4- ions in solutions made by dissolving boric acid in concentrated
sulphuric acid (p. 246).

I could not find information about "boron sulfate" of B2(SO4)3 stoichiometry, but another "sulfate" is characterised: B2S2O9
Of course, it contains no ions, but joinded tetrahedra [BO4] and [SO4] .

Thanks everyone!
DraconicAcid, that would be an acid right, I mean an acid mixed with an acid wont produce a salt
Are there any boron-sulphur compounds which are commonly known/available? (which are stable in aqueous environment)
