scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX), thermal analysis (STA), and diffuse reflectance spectroscopy (DRS). The effect of various factors such as pH, different molar ratios of precursors, temperature and time of reflux on the morphology and particle size of ZnS spherical nanostructures were investigated. The x-ray diffraction results confirmed the formation of single-phase ZnS nanoparticles with a cubic crystal structure. Field emission scanning electron microscopy (FE-SEM) was also showed that the prepared nanoparticles with molar ratio 1:1.3 (zinc : sulfur) have a spherical and homogeneous morphology. ZnS nanostructures completely were compacted by hot pressing technique under vacuum atmosphere and were investigated as a compact ceramic. With the X-ray diffraction revealed that ceramic had cubic crystalline phase. The grains size of ceramic was observed with field emission scanning electron microscopy images, which were about 1 to 3 ?m. The ceramic fabricated is a desirable candidate for use in the optical industry.
