Abstract

© The Authors, published by EDP Sciences, 2018. Barium sulfate (BaSO4) with fine sizes is important for many applications. Barium Sulfate (BaSO4) is suitable for applications as diverse as whiteness, inertness and high density. Many different approaches have been reported for the preparation of nanoparticles BaSO4 including the addition of different additives. Aims of this study to synthesize barium sulfate (BaSO4) from natrium sulfate and barium chloride with the modification of the mixing speed, temperature and additive concentration variations. This study conducted in Diponegoro University Laboratorium. The sample were characterized by a number of different methodologies, including XRD and SEM-EDS. The higher the temperature of the mass of the crust that formed more and more. The results showed a temperature of 40°C was obtained crust mass greater than at 30°C. The addition of the additive citric acid to 20 ppm does not have enough influence to lower the formation of crust mass. From the SEM image, it is clear that the particle size is less than 10 μm.
