Increasing the Melting Ability of Glass Batch by Batch Modification

Abstract:

The soda-lime glass with the composition of 74SiO₂-18Na₂O-6CaO-B₂O₃-Al₂O₃ thermodynamically requires the exploited heat of 557 kW/ ton of glass to transform raw materials into glass. The objective of this project is to modify the soda-lime glass batch by using wollastonite instead of limestone and pyrophyllite instead of aluminium hydroxide. The exploited heat of the batch with wollastonite is reduced to 546 kW/ton of glass while the batch with wollastonite and pyrophyllite is decreased to 550 kW/ton of glass. According to Batch-Free Time testing, it is found that the melting ability of both modified batches is higher than of the original batch, while the properties of glass are slightly changed. This implies that the modified batch requires a lower melting energy than the original batch.
