Product Description
Calcium hydroxide (Ca(OH)₂) is a white, alkaline inorganic powder produced by hydrating quicklime (calcium oxide).
Also known as hydrated lime, slaked lime, or milk of lime (when in suspension).
Strongly alkaline (pH ~12.4 in saturated solution) with high reactivity and fine particle size.
Widely used in construction, water treatment, agriculture, food processing, and environmental applications.
Note: CAS 12167-74-7 is a valid designation for hydrated calcium hydroxide; the more common registry is 1305-62-0 — both refer to the same product, so confirm the registry used by your buyer.

Product Application
Water & Wastewater Treatment: pH adjustment, coagulation aid, softening, and heavy-metal/fluoride precipitation.
Construction & Building: Key component of lime mortars, plasters, soil stabilization, and cementitious repair.
Agriculture & Soil: Soil pH correction (liming) and calcium/magnesium balance improvement.
Environmental & Flue-Gas: Acid-gas neutralization (e.g., SO₂ scrubbing) and sludge treatment.
Food & Chemical: Food-grade liming agent; raw material for calcium salts and fine chemicals.
Drilling & Paints: Mud additive in drilling and pigment/extender in paints and coatings.
