摘要：

Formation of transparent glass-ceramics based on crystallization of barium borate (BBO) crystals from BaO center dot B2O3 glass-systems, with and without addition of BaF2 has been investigated. Crystallization of glass-samples was done by controlled thermal heat-treatment, at nucleation and crystallization temperatures, for different times and rates. When the glasses were heat-treated at the nucleation temperature, transparent glass-ceramics containing 0.1-0.3 mu m BBO crystals were prepared. It is obvious that fluorine influences the transparency of glass-ceramics. (c) 2005 Published by Elsevier Ltd and Techna Group S.r.l.
