Lead Iodide have been grown by gel method using single diffusion method. Optimum conditions to grow these crystals have been obtained. Crystals of Lead Iodide have been withdran from the test tube in which the crystals have grown. After careful withdral of Lead Iodide, they are washed with acetone and kept under light for whole night. Then they are crushed of constant size (150 mesh). These grown crystals were characterized by XRD and thermal analysis. XRD confirms the structure of Lead Iodide as hexagonal, also the lattice parameters are closly matching with the ASTM data of Lead Iodide. Thermal analysis infers that Lead Iodide is thermally stalble crystals and does not affect by the temprature. The results of these observations are described and discussed
