In doped calcium fluoride transparent conducting powder were prepared by solid state reaction method. Structural properties of the samples were investigated as a function of various In-doping levels (x=0.00-0.04-0.05-0.06). The results of x-ray diffraction have shown that the samples are polycrystalline structure in cubic phase, with preferential orientations along the (112) for In for all samples, and show presence (111), (220), (311), (400) planes in pure CaF2 sample and The preferred orientation is (220) for pure CaF2, and we have peaks correspond to (101), (002), (110), (112), (200), (202) for In for all samples and The preferred orientation is (112) for In for all samples. The average of crystallite size is within the range [5.148-1.041 nm] for all samples. The relative intensities, distance between crystalline planes (d), crystallite size (D) and lattice parameters (a) were determined.
