Preparation of CaCO3/MgO from Bangkalan's dolomite for raw biomaterial

Abstract

Dolomite is a double salt consisting of calcium carbonate (CaCO3) and magnesium carbonate (MgO) and is one of the two forms of limestone. This dolomite can be found in the Bangkalan area, which only used as the landfill and making light stone. Existence the great potential for dolomite as a biomaterial then in this research was carried by making CaCO3/MgO from dolomite using a simple calcination method at 600C, 700C and 800C for one hour. The results of the calcination then carried out of XRD characterization. From the results of XRD found that the CaCO3/MgO phase was formed optimally at a temperature of 700C.
