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 sol-gel 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 degrees C). For all the M...
