Calcium Hydroxide, commonly known as Hydrated Lime or Lime Powder, is a fine, white, odorless powder produced by hydrating quicklime (CaO). It is widely used in water treatment, flue gas desulfurization, construction, food processing, and various chemical manufacturing processes. Lime powder acts as a pH adjuster, flocculant, and neutralizing agent, and plays a key role in environmental and industrial applications due to its strong alkalinity and low solubility in water.
