Abstract
Hidroksiapatit telah dibtlat melalui sintesis hidrotennal dengan kalsium karbonat sebagai material awal. Bubuk ruah dari kulit telur ayam Gallus sp. dan Tel/ina sp. digunakan sebagai sumber kaJsium karbonat. Kulit telur Gallus sp. mengandung 84,38 o/oCaC<h, dalam bentuk kalsit, sedangkan cangkang Tel/ina sp. memiliki 90,25 o/oCaCO.h ru&lam bentuk aragonit. Kalsium fosfat dibuat dengan mencanpur kalsium karbonat dari kulit/cangkang (dengan varias~ bubuk kulit telur ayarn saja. bubuk cangkang kupang saja. W!n campuran keduanya) dengan diamonium hidrogen fosfat, (NH.)2HP04, dalam autoclave hidrotermal stainless steel pada 20(fC selama 12 jam. Karakteristik kimia dan struktur dari bubuk yang disintesis diamati dengan met ode XRD dan FT-IR. Hasil pengamatan menunjukkan bahwa bubuk yang diperoleh dari basil sintesis merujuk pada senyawa hidroksiapatit terkarbonasi tipe-B, dalam bentuk heksagonal.

Hidroxyapatite were prepared by hydrothennal synthesis with calcium caroonate as starting material. Powder of bulk Gallus sp. (egg) shell and Tel/ina sp. (clam) shell were used as a source of calcium carbonate. The shell of Gallus sp. compose of about 84,38 o/oCaC03, in calcite form, whereas Tel/ina sp. constitute of 90.25 o/oCaC~, in aragonite form. Calcium phosphates fonned by mixing calcium carbonate from the shells with diammonium hydrogen phosphate, (NH.)2HP04, in a stainless steel hydrothermal autoclave at 2(1()0C for 12 hours. Characteristics structural wd chemical of the synthesized powder were then investigated by XRD and Ff-IR methods. Results showed that the as-synth:sized powders are prekntially carbonated hydroxyapatite of the IB-type, in hexagonal form.
