Innovative transparent tellurite polycrystalline ceramics are demonstrated to be simply elaborated by full and congruent crystallization of the 75TeO2–12.5Bi2O3–12.5Nb2O5 parent glass. The low temperature tellurite glass elaboration and its stability both enable the preparation of scalable tailor-shaped ceramics with high refractive index, transmission in the near infrared range up to 5.5 μm, and promising mechanical/thermal properties.
