Titanium (III) phosphide is an inorganic chemical compound consisting of the group of the phosphides.

Production and representation

Titanium (III) phosphide can be obtained by synthesis from the pressure elements.

When it can win in the implementation of monophosphane with titanium (IV ) chloride at 750 ° C. Also possible is the electrolytic preparation of a nearly stoichiometric composition of titanium ( III) phosphide powder at 860 ° C from a solution of 10% titanium dioxide in a mixed melt containing only di - and metaphosphate or sodium chloride and lithium fluoride.

Finely powdered titanium hydride can be implemented at 800-1000 ° C with a monophosphane / hydrogen mixture to phosphides with smaller phosphorus content ( TiP0 0.1-0, 6).

Properties

Titanium ( III) phosphide is a black and gray, metallic -looking and thermally very stable powder by acids even when heated little vulnerable. It has a hexagonal crystal structure with space group P63/mmc (a = 3.487 Å, c = 11.65 Å).

Use

Titanium (III) phosphide is used as a catalyst in organic synthesis.
