A New Fused Magnesium Chloride Containing Refining Flux Based on a Ternary System

Summary:The major cost factor in the production of fused refining fluxes is raw materials and in particular the cost of potassium chloride, which because of its role in fertilizer production has been subject to large price increases in the period 2008-2009, having risen by more than 350%. As demand for potash for world food production and bio-fuels is increasing again with the recovery in the global economy further price rises are expected, with the price having risen already by 43% from November 2010 to July 2011. A program of work has been undertaken to develop an alternative flux based on a ternary system comprising magnesium chloride and potassium chloride; where the potassium chloride is partially replaced with sodium chloride. The results of a study of the thermodynamics together with laboratory measurement of viscosity, interfacial tension and differential thermal analysis are presented.
