Hidroxyapatite (HAp) merupakan salah satu biomaterial yang banyak diaplikasikan dalam dunia medis untuk membuat implant jaringan tubuh terutama tulang dan gigi sehingga kemurnian produk HAp memegang peranan yang cukup penting. Agar diperoleh HAp dengan kemurnian tinggi, kinetika reaksi pembentukan HAp harus diketahui secara jelas. Metode yang digunakan untuk memperoleh kinetika reaksi HAp adalah dengan analisis TG-DTA yang dilakukan pada dua jenis prekursor HAp yaitu asetat dan nitrat. Metode TG-DTA tersebut dilakukan dengan memanaskan prekursor HAp dengan variasi laju pemanasan 10, 15, 17, dan 20 oC/menit. Hasil analisis TG-DTA menunjukkan bahwa reaksi dekomposisi prekursor asetat dan nitrat membentuk HAp masing-masing terjadi pada suhu 659 oC dan 560 oC. Hasil fitting parameter kinetika menunjukkan bahwa energi aktivasi pembentukan HAp pada prekursor asetat sebesar 161,56 kJ/mol dengan model kinetika Normal Grain Growth sedangkan pada prekursor nitrat sebesar 374 kJ/mol dengan model kinetika Johnson-Mehl-Avrami.
