Chemical oxides analysis from Azara Baryte

Abstract:  Physical and chemical analysis of the two samples A and B of Azara baryte were conducted, such as moisture content, loss on ignition and elemental composition by the use of atomic absorption spectrophotometer(AS S) and flame photometer. The oxides values in 1.000 gram sample of each element were obtained. Sample A (lower layer): moisture content = 0.020, loss on ignition = 0.060, Na2O = 0.250, K2O = 0.015, CaO = 0.014, MgO = 0.018, Fe2O3 = 0.029, SiO2 = 9.310, BaO = 89.630, Al2O3 = 6.200 Sample B (upper layer): moisture content = 0.030, loss on ignition = 0.040, Na2O = 0.030, K2O = 0.001, CaO = 0.006, MgO = 0.030, Fe2O3 = 0.028, SiO2 =18.12, BaO = 65.020, Al2O3 = 16.120. The result of this analysis revealed that the Azara baryte could use as source of inorganic chemical oxides and for the production of some laboratory chemicals such as barium sulphate and aluminum oxides.
