Comparative Study of Physical and Optical Properties of Glasses from SiO₂ and Napier Ash

Abstract:

The aim of this paper is comparative study of physical and optical properties of glasses from SiO₂ and Napier ash (Pennisetum purpureum ash (PA)). PA was selected from biomass power plant. Selected ash was sintered at different temperature (500, 800 and 1000 °C). The glasses containing in formula 55SiO₂: 20Na₂O : 1.0Al₂O₃ : 13B₂O₃ : 6.3CaO : 0.2Sb₂O₃ : 4.5BaO. It has been found that the density and refractive index of PA glasses increases with a increasing sintering temperature. However, SiO₂glass has density and refractive index more than PA glasses every different sintering temperature. The spectra of PA glass are shown cut-off wavelength around 330 nm at all glass samples.
