Phase behaviour of manganese-doped biphasic calcium phosphate ceramics synthesized via sol-gel method

Manganese-doped biphasic calcium phosphate (Mn-doped BCP) powders have been synthesized via solgel technique. The Mn-doped BCP powders were studied for their phase behaviour at different concentrations of Mn (0, 0.01, 2, 5 and 15 mol%) and calcination temperatures (500–1200 ◦C). For all the Mn conce...
