Investigation of Melting Behavior of Low-Enthalpy Glass Batches

Abstract:

Batch modification with low-enthalpy raw materials is the effective approach for reducing the glass melting energy. In the previous study, it was found that introducing wollastonite (CaSiO₃) as a source of CaO instead of calcium carbonate (CaCO₃) in the soda-lime glass batch can fasten the melting process. It is because the modified batch with CaSiO₃has lower chemical heat demand, ΔH^o_chem, which is equivalent to the standard heat of batch-to-melt conversion. In order to investigate the kinetic property of the modified batch, the melting behaviour of 2 kg modified batch was studied. The results showed that the temperature of the modified batch increased at a faster rate than the original batch. The properties of the glass from the modified are also similar to the original batch.
