The β-tri-calcium phosphate (β-TCP) is a calcium phosphate compound also called whitlockite. This form is more widely used because of its chemical stability, high mechanical strength and better bio-sorption when compared with α-Tri-calcium-phosphate. β-tri-calcium phosphate in this study was obtained from reactions of calcium oxide and phosphoric acid by precipitation method. Precipitation at 50 °C while sintering at 600, 700, 800, 900, and 1000 °C, in the sintering range of 1-5 hours. Green mussel shell has calcium carbonate (CaCO 3 ) content 60-70 % then calcined at 1000 °C to get calcium oxide (CaO). The result shows that β-tri-calcium phosphate optimum reached of 72% at sintering temperature 1000 °C for 5 hr sintering time. The crystal structure of β-tri-calcium phosphate formed is a rhombohedral crystal with a Ca / P ratio mole of 2.72
