The silver chloride powders hydrate at 100 ℃ in the deionized water for different hydration time. Bulk-Type silver chloride after melting at 500 ℃ and solidification was produced, and then the silver chloride plate was made by pressure. We discussions any effect on lattice constant change and silver chloride plate characteristic with microstructure, surface energy and transmittance with different hydration time. The results show that the lattice constant in increased with the hydration time thus reduced the surface energy of the Bulk-Type silver chloride and silver chloride plate. And using X-ray analysis to know Bulk-Type silver chloride contained silver nitrate, and silver chloride will precipitate silver by thermal decomposition at high temperature. Those will affect silver chloride on microstructure. The microstructure types were equiaxed grains, radial grains and feathery-like grains. The effect of thermal decomposition of silver chloride and precipitated silver reduced with increasing hydrate time. Finally, silver chloride has low surface energy and high transmittance in infrared light.
