Incorporating sugarcane bagasse ash into Al2O3 ceramic tapes

High‐temperature co‐fired ceramic (HTCC) technology aims to incorporate fluxing materials into ceramic tapes to decrease the sintering temperature. In this context, we incorporate waste from sugarcane bagasse ash (SCBA) into alumina (Al2O3) tapes. We report an experimental investigation of the struc...

Description
Summary:High‐temperature co‐fired ceramic (HTCC) technology aims to incorporate fluxing materials into ceramic tapes to decrease the sintering temperature. In this context, we incorporate waste from sugarcane bagasse ash (SCBA) into alumina (Al2O3) tapes. We report an experimental investigation of the structural, physical, mechanical, and dielectric properties of the Al2O3 tape with the addition of the SCBA waste. The tape casting technique prepared the ceramic tape. The materials under study were characterized by rheology, thermogravimetry, dilatometry, X‐ray diffraction, scanning electron microscopy, relative density, Vickers microhardness, mechanical resistance, and dielectric measurements. The dilatometry results confirm that the addition of the SCBA waste remarkably reduces the sintering temperature of the Al2O3 tape to 1200°C. The physical, mechanical, and dielectric properties are improved with the addition of the SCBA waste, which makes our discoveries attractive from an environmental and economic point of view. Besides, the stabilization and high dielectric constant of the Al2O3‐SCBA tape becomes a promising material for aircraft turbine applications.
