Transparent glass-ceramics containing nanorods are attractive for many applications. In this work, transparent aluminoborosilicate glass-ceramics containing aluminum borate nanorods are reported. Effects of Al 2 O 3 and SiO 2 concentrations on the thermal properties and crystallization of aluminoborosilicate glasses are studied. It is found that lithium aluminosilicate nanocrystals and Al 4 B 2 O 9 nanorods are co-precipitated in glasses with Al 2 O 3 /SiO 2 molar ratios of 0.29 and 0.33, and only Al 4 B 2 O 9 nanorods are precipitated in glasses with Al 2 O 3 /SiO 2 molar ratios of 0.375 and 0.42. Precipitation of these nanocrystalline phases leads to the enhancement in Vickers hardness. Glass-ceramics with Al 2 O 3 /SiO 2 molar ratios of 0.375 and 0.42 are highly transparent in the visible region due to the small size of the Al 4 B 2 O 9 nanorods precipitated inside.
