Nanopowders of CaF2–SrF2–NdF3 were synthesized by direct precipitation method. X-ray powder diffraction and transmission electron microscopy observations indicated that the powders were single phased with mean particle size around 20nm. CaF2–SrF2–NdF3 transparent ceramic was fabricated by hot-pressed (HP) method at the temperature of 800°C under pressure of 30MPa. Micrograph of the transparent ceramic...
