Abstract
Magnesium silicate (MgSiO₃) is an inorganic compound formed through the reaction between magnesium and silicate. This study aims to optimize the synthesis process of magnesium silicate from bittern using the precipitation method. Bittern, a by-product of the salt industry, is rich in magnesium ions. In this research, magnesium hydroxide (Mg(OH)₂) was first produced by reacting bittern with sodium hydroxide (NaOH), and then further reacted with sodium silicate (Na₂SiO₃) to form magnesium silicate (MgSiO₃). Variations in the molar ratios of NaOH:MgCl₂ and Mg(OH)₂:Na₂SiO₃ were applied to determine the optimal conditions for product formation. The analysis results showed that the highest yield of 69.969% was obtained at a molar ratio of NaOH:MgCl₂ = 1:2 and Mg(OH)₂:Na₂SiO₃ = 1:1. Characterization using X-Ray Fluorescence (XRF) revealed that the optimal magnesium silicate produced contained 17% MgO and 71% SiO₂. This study demonstrates that optimizing the reactant molar ratio plays a crucial role in improving the efficiency of magnesium silicate production and provides potential for its application in various industries.
