A comprehensive study of the batch‐to‐melt (BtM) conversion process was carried out on a single high‐boron alkaline earth aluminosilicate glass composition, which is relevant to manufacturing high‐performance fiberglass for high‐end electronic applications. In the study, we used several techniques to trace the BtM process from room temperature up to 1400°C, namely isotherm batch heat‐treatment, X‐ray diffraction (XRD), hot‐stage microscopy (HSM), high‐temperature differential scanning calorimetry (DSC), and Fourier transform infrared (FT‐IR). In the BtM process, the intermediate aluminum borate phase (Al4B2O9) between 1000 and 1100°C was identified. The formation of Al4B2O9 is explained in conjunction with the dihydroxylation of kaolin. For the first time, the potential use of the FT‐IR method in studying the BtM process was demonstrated, including the dissolution of sand above 1100°C. [ABSTRACT FROM AUTHOR]
