Sequential elucidation of the β-Ca 3 (PO 4 ) 2 /TiO 2 composite development from the solution precursors
The sequential formation of β-Ca (PO ) /TiO composites with assorted ratios synthesized from the solution precursors is described. The phase evolution of the synthesized powders to yield a composite during progressive heat treatments is determined through a set of analytical techniques. Investigatio...

crystallizes at ∼800 °C and its subsequent stability is retained until 1300 °C. Besides, a gradual phase transition of a- → rutile TiO
(r-TiO

plays a crucial role in the attainment of dense and pore free microstructures of β-Ca
