| Abstract: | The present study reports the synthesis and characterization of an eco-friendly, crack-resistant borosilicate glass utilizing rice husk ash (RHA) as a sustainable silica source. Silica extracted from rice husk through controlled calcination and acid precipitation was found to be amorphous, highly pure, and particles are small in size, as confirmed by XRD, SEM-EDS, and FTIR analyses. This bio-derived silica was subsequently used to prepare borosilicate glass of composition 63SiO 2 –12B 2 O 3 –15Na 2 O–10CaO via melt-quenching method. The resulting glass exhibited high optical transmittance (∼90%) in the visible region and an optical band gap of 3.3 eV, comparable to that of commercial display glass. Differential thermal analysis (DTA) revealed a glass transition temperature (T g) of 512 °C and a thermal stability parameter (ΔT ≈ 95 °C), suggesting excellent resistance to devitrification and suitability for fiber drawing. The Vickers microhardness of 3.57 GPa and the yield stress of 11.9 GPa measured indicate a dense and mechanically stable glass network. Furthermore, dielectric analysis showed a dielectric constant in the range ε ′ = 4.6–5.5 with low dielectric loss, tan δ = 0.02–0.06, confirming its insulating nature. The results confirm that RHA-derived silica can replace commercial silica for glass production successfully, therefore presenting a low-cost, energy-efficient, and greener alternative for optical and display applications.
