Still no luck finding these. I can't find them anywhere in the web, I have emailed suppliers and manufacturers of Titanium(IV) Chloride, the Chlorine Chemistry Division and even a few professors at my old University and a few other Universities with no luck.
I find it hard to believe that the information is so hard to find. Titanium(IV) Chloride is a widely used chemical in both research and industry, so its equilibrium phase diagram should be readily available. Titanium(III) Chloride and Titanium(II) Chloride are not as widely used, but there should at least be a calculated diagram for both of them even if an experimental one isn't available.
