Abstract

The aim of this work was to fabricate corrugated lightweight structures from green tapes of Li2O–ZrO2–SiO2–Al2O3 (LZSA) glass–ceramics. The green tapes were cast, thermopressed, corrugated, and sintered at 800 °C for 1 h, yielding low porous and homogenous microstructures confirmed by electron microscopy analysis. Dilatometric analysis demonstrated three linear regions, each one exhibiting a specific thermal expansion coefficient (TEC) in the 25–800 °C temperature range. It was also concluded that 600 °C was the critical temperature above which the LZSA glass–ceramic structure could not be assembled. The fabricated bodies were also characterized macroscopically and geometrically to verify the integrity and the morphology of the structures.
