N2 - Glass-ceramics (GC) consisting of nano-sized Nb-dielectrics were fabricated in BaO-Na 2O-P 2O 5-Nb 2O 5 system, and their crystallization and physical features were studied. Precursor of 0.67(2BaO-0.5Na 2O)-1P 2O 5-2.5Nb 2O 5 glass co-crystallized Ba 2NaNb 5O 15 (BNN) and NaNbO 3 phases, which are about 10 nm in size, and resulting GC possessed an optical transparency comparable to the precursor glass, and optical band-gap of the GC was close to that of BNN. It is suggested that the fabricated GC is not merely a GC with transparency but Nb-dielectric GC, in which light scattering due to the crystallized phases evolution is minimized, i.e., practically transparent GC material.
