Modelling of the various processes of glass batch melting is an important tool in the design & optimisation of commercial melting tanks, & reaction thermodynamics & kinetics are a key component of any comprehensive model. While thermodynamic parameters can be calculated using commercially available databases, kinetic data are more complex as they are influenced by factors such as grain size, texture, mixing & compaction, & are best obtained using experimental methods. This study is therefore measured the kinetics of crystalline phase formation in borosilicate/E-glass batches (CaSiO3, Ca2SiO4, CaAl2Si2O8) & SLS batches (Na2Ca(CO3)3, Na2SiO3, Na2Ca2Si3O9) between 500 & 1300 degrees using in situ x-ray diffraction. Solid state reactions followed Johnson-Mehl-Avrami equations for diffusion controlled growth.
