Judul: Perubahan Fase Padat pada Pembentukan Hidroksiapatit Akibat Suhu
Abstrak: Hidroksipatit [HAp, Ca10(PO4)6(OH)2] adalah salah satu bahan biomaterial yang dapat digunakan untuk implan tulang buatan karena memiliki komposisi yang sama dengan tulang manusia, bersifat bioaktif dan biokompatibilitas yang baik. HAp sintesis dengan menggunakan metode kering dan metode kering modifikasi sonikasi dari reaksi antara serbuk CaO hasil pemanasan cangkang kerang darah 1200 ºC selama 2.5 jam dan diamonium hidrogen fosfat (NH4)2HPO4 sebagai sumber fosfat. Difraktogram sampel menggunakan metode kering selama 2.5 jam pada suhu 400 ºC menghasilkan fase HAp, β-TCP, AKA, OKF, Ca(OH)2, dan CaO, pada suhu 600 dan 800 ºC terbentuk fase HAp, β-TCP, AKA, OKF, dan CaO, pada suhu 1000, 1200, dan 1250 ºC (serbuk dan pelet) terbentuk fase HAp dan β-TCP. Difraktogram sampel bersumber CaO cangkang kerang darah dan CaO komersial terbentuk fase HAp, β-TCP dan AKA. Metode kering-sonikasi (pelet) pada suhu 400 1250 serta 1250 ºC (serbuk) selama 3 jam menghasilkan fase HAp, β-TCP. Pada sampel 1250 ºC (serbuk) metode kering-sonikasi menunjukkan puncak tertinggi 2θ adalah hidroksiapatit dengan nilai 2θ 31,835º dan 32,918º, dan memperlihatkan morfologi permukaan yang lebih halus dan homogen berdasarkan mikroskopi payaran elektron.
