Abstract
Have been carried out making porous hydroxyapatite (HAp) with base material of fish bones waste, as porogen agent chitosan by themethod of calcination at a temperature of 1100 ° C for 5 hours. Thermogravimetric analysis performed by Simultaneous Thermal Analyzer (STA), the phase identification was done by X-Ray Diffractometer (XRD) and microstructure was analyzed by Scanning Electron Microscope (SEM). Thermogravimetric analysis showed the peak of weight loss at 365.6 ° C and after 500 ° C weight loss does not occur again. XRD pattern indicates the presence of hydroxyapatite phase on the raw fish bones and fish bones after calcined at 1100 °C for 5 hours. SEM results showed inter particle porous microstructure on raw fish bones and after calcining 1100 °C, 5 hours with a particle size of about 0.1 - 1.0 μm. After the addition of chitosan pores between the particles are formed more evenly and clearly. Keywords: Fish bone, Hydroxyapatite, Chitosan, XRD, SEM.
