Calcium Hydroxide Supplier From Turkey & Dubai (UAE) | Bulk Hydrated Lime Export
Understanding Calcium Hydroxide
Calcium hydroxide (Ca(OH)₂), widely recognized as hydrated lime or slaked lime, is a white, odorless alkaline powder produced through the precise hydration of calcium oxide (quicklime). With a molecular weight of 74.09 g/mol and a CAS number of 1305-62-0, this versatile inorganic compound exhibits a characteristically high pH of 12.4 in saturated solution — making it one of the most effective and economical alkaline chemicals available on the market today.
What sets calcium hydroxide apart from competing alkaline agents like sodium hydroxide or sodium carbonate is its exceptional balance of performance, safety, and cost-efficiency. It delivers powerful neutralization capacity while remaining significantly easier to handle, less corrosive to equipment, and more environmentally responsible than many alternatives. These advantages explain why demand continues to grow across virtually every industrial sector.
