This work reports some experimental results regarding to a Li2O-ZrO2-SiO2-Al2O3 (LZSA) sinteredglass-ceramic material obtained by roll pressing of glass powders (mean particle size ≈ 5 μm) withan added (7 wt.%) inorganic material (bentonite) as binder. The composition was characterizedusing chemical analysis, laser-scattering particle size analysis, DTA, XRD, thermal expansion,modulus of rupture (MOR) and deep abrasion (DA) measurements as well as density measurementsand SEM observations. From the results it was verified that the glass-ceramic materials obtained bysintering and controlled crystallization, in the 850-1030°C temperature range, of glass powders,have properties and characteristics decisively better than those of other traditionally used materials.It is concluded that roll pressing technology is a potential candidate to produce sintered glassceramicsfor many applications, such as, for example, large sheets panels for electrical and thermalinsulation
