Effect Of Aging Time, Calcination And Sintering Temperature To Β-Tricalcium Phosphate (Β-Tcp)

β-TCP has a higher resorption rate and it is normally considered as a biodegradable materials that allows bone growth and replacement. In this study, β-TCP was synthesized through sol-gel method. Thus, the objectives of this study were to determine the effect of aging time and temperature towards th...
