Abstract

Hydroxyapatite (HAp) is the main material of bone structure which has chemical formula Ca10(PO4)6(OH)2. In this research, HAp synthesis use precursor calcium from crab shells and phosphate from H3PO4. Phosphate addition is done in single drop and wise drop. The calcinations of crab shell were done at 1000 °C for 5 hours. The FTIR analysis showed that there were functional groups of OH, CO32-, PO43- and Ca-O. The XRD analysis of HAp showed that synthesis with wish drop method has the main phase of HAp and second phase is apatite carbonate. HAp that synthesized by single drop besides produce those phase also produce tricalcium bis(orthophosphate) phase. The synthesized HAp using the wise drop method has a larger surface area and pore volume but has a smaller pore size than that synthesis by using single drop method. The analyze morphology showed that HAp that synthesis using the wise drop method there is an agglomeration in morphology and the synthesis using single drop method has a smooth morphology with pores spread evenly
