Microstructure development and optical properties of Fe:ZnSe transparent ceramics sintered by spark plasma sintering
Abstract
Fe:ZnSe transparent ceramics were prepared by spark plasma sintering. Fe:ZnSe powders synthesized via co‐precipitation yielded well‐dispersed particles with an average particle size of 550 nm. These powders were in the cubic phase Fe:ZnSe, indicating the successful substitution of Fe2+ for Zn2+. The highest relative density, 99.4%, was obtained by increasing the pressure and sintering time. The effects of sintering temperature, pressure, and time on the microstructure of SPS prepared ceramics were presented by micrographs. With increasing sintering temperature, from 600°C to 900°C, the average grain size increased from 2+ ions at around 3 μm, which was red‐shifted compared to Fe:ZnS transparent ceramics. Fe:ZnSe transparent ceramics have a reddish‐brown color and it could be a promising mid‐infrared laser material.
