Fabrication of glass-ceramics containing nano-sized lithium niobate crystals

The glass-ceramics from (95-x)LiNbO3-xSiO2-5Al 2O3 system where 15≤x≤55 were fabricated by the incorporation method. This method requires the calcination process of the LiNbO3 powder before mixing with theglass formers which in this case are xSiO3-5Al2O3 oxides with various x values corresponding to...
