영문 초록

Optimal synthetic conditions of barium sulfate were investigated from the viewpoint of yield and bulkiness according to a randomized complete block design proposed by Box and Wilson. Barium chloride and Sodium sulfate were utilized as reactants in order to prepare barium sulfate in this stud7: The optimum Synthesis conditions of barium sulfate obtained from this study are as follows; Reactant temperature; 60∼75oC (viewpoint of yield) and 60∼71oC(viewpoint of bulkiness). Concentration of two reactants; 12.7-14.4% (viewpoint of yield) and 5∼10.5% (viewpoint of bulkiness). Mole ratio of two reactants, [BaCl2]/[Na2SO4]; 1.62-1.96 (viewpoint of yield) and 2.0 (viewpoint of bulkiness). Reacting time; 13∼ 15 minutes (viewpoint of yield) and 12-14 minutes (viewpoint of bulkiness). Drying temperature of product; 86∼ 100oC (viewpoint of yield) and 60oC (viewpoint of bulkiness).
