摘 要：<正>The structural rearrangement of quenchedtitanate glasses reheated at Tg. was investigated by ESR andIR spectroscopies. From the ESR observations it is suggestedthat the structure was readjtsted and became more compactafer the heat-treatment. A removal of residual vacancies isrelated to the diffusion of oxygen ions. The combination ofmore oxygen with titanium ions to form titanium-oxygenpolyhedra and the transformation of boron-oxygen groups areconfirmed from IR spectra. Some physical properties are improved after heating.
