In this study, it was investigated the optimum conditions (extraction temperature and extraction period) for the production of sodium metaborate dihydrate (NaBO2.2H2O) by the reaction of ulexite (NaCaB5O9·8H2O) with trona (NaHCO3-Na2CO3·2H2O) and lime (CaO). The optimum extraction conditions were determined as 50 °C and higher temperature; 6 h and longer extraction time. The characterizations of the product (sodium metaborate dihydrate crystals) were performed by thermogravimetric (TG-DTG) and X-ray diffraction (XRD) analyses. In addition, the percent purity of the product was found to be 96% by using a conductometric method.
