Abstract

The role of TiO//2 as a nucleating agent in a binary barium borate glass system of the molar composition BaO. 4B//2O//3 was investigated using transmission electron microscopy. X-ray and electron diffraction methods were used to identify the precipitated crystalline phases. Phase separation into two immiscible glassy phases was found to be a precursor for crystallization in all the glasses with TiO//2 additions. TiO//2 enhanced nucleation in this glass and produced a coarse grained glass ceramic with subsequent heat treatments.
