“…In recent years, different glass-based scraps have been used for production of GFs. The majority of the studies on porous ceramic materials focused on the potential of recycling glass, [6][7][8][9] and others on the possibility of producing materials with different thermal properties. [10][11][12][13] When evaluating insulation of ceramic materials, mechanical properties are usually ignored.…”

A glass foam (GF) of high specific compressive strength (12.17±1.91 MPa g−1 cm−3) and low thermal conductivity (.121±.001 Wm−1 K−1) was produced from waste glass of photovoltaic module, eggshells, and bentonite clay. The influences of the amount of clay and heat‐treatment temperature on the GFs final properties were assessed. X‐ray diffraction results and the data of microscopic analyses demonstrated that addition of clay affected the structure and porosity of the GFs, and consequently their mechanical properties. On the basis of the mechanical property (density), the GF that composed of 80% waste glass, 10% clay, and 10% eggshell at the sintering temperature of 900°C was the best. The GFs reported in this study could serve as promising insulators in situations where high load support is required.
