  • Appearance: White powder
  • Odour: Odorless
  • Common Concentrations: Technical, hydrated lime, or slaked lime (varies depending on use)
  • Density: Approx. 2.24 g/cm³ (solid form)
  • Melting Point: ~580°C (decomposes at high temperatures)
  • Boiling Point: Decomposes before boiling
  • Solubility: Slightly soluble in water (1.73 g/L at 20°C); forms limewater
  • Stability: Stable under normal conditions; reacts with acids and carbon dioxide
  • Hazard Nature: Strong alkaline; corrosive; can cause skin and eye irritation

Functional Properties
  • Strong alkaline agent for neutralization and pH adjustment
  • Softens water by precipitating calcium ions
  • Used as a flocculant in water and wastewater treatment
  • Reacts with carbon dioxide to form calcium carbonate
  • Facilitates chemical reactions such as saponification and sugar refining
  • Acts as a stabilizer and buffering agent in soils and industrial processes

Common Applications

Water & Wastewater Treatment
  • Adjusts pH, softens water, and removes impurities via precipitation
  • Used in sewage treatment to neutralize acidic effluents
Construction Industry
  • Key component of mortars, plasters, and cements
  • Used for soil stabilization and lime-based plastering
Chemical Manufacturing
  • Reactant in production of calcium salts, bleaching powder, and other chemicals
  • Used in sugar refining to remove impurities
Environmental Applications
  • Neutralizes acidic soils and acid mine drainage
  • Treats industrial effluents and controls odor
Food & Beverage Industry
  • Used in food processing as a firming agent (e.g., in canned vegetables)
  • Adjusts pH in certain food production processes

Advantages

  • Cost-effective and widely available
  • Strong neutralizing and alkaline properties
