- 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.
