摘要: Crystalline phases of titanium (IV) phosphate have been obtained from titanium(III) chloride in phosphoric acid solutions. The {alpha}-titanium synthesis is possible at low temperature (60--80 C). {gamma}-Titanium by reflux with very concentrated 3--5 hours oxidation O{sub 2}. influence these reactions several factors (concentration reagents, molar ratio P:Ti the reaction mixture, and reaction) was studied. formation takes place steps through sequential amorphous titanium(IV) phosphate, {gamma}-titanium and/or a semicrystalline hydroxophosphate, Ti(OH){sub 2}(HPO{sub 4}){center_dot}H{sub 2}O.
