Abstract: In mold fluxes, fluorine is generally added to reduce viscosity and solidification. The fluorine however, tends to cause corrosion of the casting machine and leads to environmental pollution. To potentially rid this design of these issues, researchers in this study examined the Fluorine-free mold flux, in a specific glass system. Properties such as viscosity, thermal conductivity and crystallization behaviour were all analyzed and compared to the values for the commercial mold flux containing fluorine. A new optimized composition yielded similar properties and behaviour patterns as the commercial mold fluxes.
