Preparation and Properties of Glass Produced from Palm Ash

In this paper, palm petiole ash (PPA) in Thailand was calcined in different temperatures and their structures and compositions were analyzed. The glasses from each PPA were prepared by melt-quenched technique and investigated their optical and physical properties. The results show that, the major compositions of PPA are SiO2 and CaO, MgO, K2O and P2O5. The structures of PPA are low-quartz phase in all calcining temperatures. The tridymite phase was appeared at 800 and 1,000°C. Glasses from PPA were produced and showed light yellow-brown color. The results are similar in all samples, correspond with absorption spectra from UV-Visible spectrophotometer.
