Abstract Transparent and homogeneous tantalum phosphate glasses were prepared in the binary system (100‐ x )NaPO 3 ‐ Ta 2 O 5 with varying from 10 to 50 mol%. Thermal, structural, optical properties, as well crystallization mechanisms, investigated by thermal analysis, X‐ray diffraction, Fourier‐transform infrared spectroscopy (FTIR) Raman spectroscopies, absorption, transmission electron microscopy terms of content. FTIR results support insertion chains [TaO 6 ] polyhedra cross‐linking...
• New glass-ceramics obtained from glass with composition 70GeO 2 .20Ta O 5 .10K O. Our have good optical quality and are promising as rare-earth hosts. Appropriate annealing successfully controlled crystallization process.
