Abstract

Abstract. The damage of bone tissue can cause malfunction of human body system, such as demineralization of calcium and phosphate. New method of the use of biomaterial as bone implant can eliminate re-operation on the patient. The biomaterial was hydroxiapatite made of bio ceramics. The bio ceramic was limestone. The hidroxiapatite characteristic was investigated as a function of sintering time, 3, 4 and 5 hours and different sintering temperatures of 600, 700 and 800 C. The preparation of composite was including crushing, meshing, grinding using ball mill and sintering at different sintering times and temperatures. The characterisation of the hydroxipatite was carried out using XRD, SEM and EDS. The hydroxiapatite was made of limestone shows the similarity of x-rays diffarction between commercial hydroxiapatite and hydroxiapatite made of limestone. This indicates that the local hydroxiapatite can replace the expensive imported hydroxiapatite. The SEM micrograph shows the agglomeration of particle increase with sintering temperature. The EDS result show that the highest ratio of calcium and phosphor was 2.33. The calcium percentage in local hydroxiapatite was decreased as the sintering time increased.
