The glass bottle waste was chemically characterized by X-ray fluorescence (XRF) and four formulations were developed with different fractions of glass bottle waste, wollastonite, and corundum. The as-prepared specimens were prepared by pressing and sintering at 1160 and 1220 °C. The linear shrinkage, flexural strength, density, abrasion wear, water absorption, microstructural aspects, and microhardness of the sintered specimens were determined. The results showed that the formulation containing 50 wt% of corundum and 30 wt% of glass bottle waste had the best wear resistance (0.05 g cm-2 for the sample sintered at 1160 °C and 0.04 g cm-2 for the sample sintered at 1220 °C).
