Glass-ceramic materials were developed from gabbro including MgO and Al_2O_3 additives. Heat treatments for phase transformation from glassy matrix to glass-ceramic were carried out at 1000C for 3 h. X-ray diffraction studies conducted on the glass-ceramic samples revealed that the phases formed in the glass-ceramics were cordierite, anorthite, diopsitic augite, forsterite and andesine. Glass and glass-ceramic materials were tested for wear properties against a harder alumina counterface using by a ball-on-disc tribometer at dry sliding condition. Wear tests were realized under the loads of 2.5, 5, and 7.5 N and at the sliding speeds of 0.1, 0.2, and 0.3 m/s. Wear rate of the glass and glass-ceramics ranged from 7.324 × 10^{-7} and 2.150 × 10^{-3}-9.971 × 10^{-7} and 4.982 × 10^{-5} mm^3/m, respectively. It was shown that the crystallization treatment caused the decrease of wear rate.
