Abstract
Kalsium karbonat presipitat (PCC) bersifat polimorfi mempunyai 3 fasa yang berbeda yaitu fasa kalsit, vaterit dan aragonit. PCC disintesis dari batu kapur alam Desa Tuwiri Wetan, Tuban, Jawa Timur dengan metode pencampuran larutan. Larutan CaCl2 dicampurkan dengan larutan Na2CO3 untuk menghasilkan endapan CaCO3 dengan menggunakan variasi temperatur 30C, 40C, 60C dan 80C dan variasi konsentrasi larutan 0,125M; 0,25M; 0,375M; dan 0,5M..Hasil karakterisasi dengan XRD dan SEM menunjukkan bahwa pembentukan fasa dan morfologi partikel dipengaruhi oleh variasi temperatur reaksi dan konsentrasi larutan. fasa kalsit terbentuk pada temperatur kamar dan fasa campuran kalsit, vaterit dan aragonit terbentuk pada temperatur 40C. Morfologi yang terbentuk adalah rhombic (kotak), spindle – like dan rod – like (batang).
======================================================
Precipitated Calcium Carbonate (PCC) is polymorph had three different phases, namely calcite, vaterite and aragonite. The PCC synthesis of limestone from Tuwiri Wetan village, Tuban, East Java by solution route method. CaCl2 solution was mixed with Na2CO3 solution, then obtained CaCO3 using variation of temperatures 30C, 40C , 60C and 80C and 0,5M; 0,375M; 0,25M; and 0,125M concentration. The characterization results using XRD and SEM showed that phase and morphology formation. Calcite phase formed at room temperature and mixed calcite, vaterite, and aragonite phase at temperature 40C. The formed morphology are rhombic, spindle-like, and rod-like.
