Calcium Hydroxide Powder belongs to the family of alkaline earth metal hydroxides, specifically as a hydrated form of calcium oxide. Known commonly as slaked lime, this white powder is a fundamental chemical in several industrial sectors. It serves as a critical agent to adjust pH levels, particularly where strong alkalinity is necessary. Across Kenya, Uganda, Tanzania, and the broader East African region, Calcium Hydroxide Powder is indispensable in water treatment plants to neutralize acidity and remove impurities.
Industries like construction use it extensively in mortar and plaster formulations, exploiting its chemical reactivity for setting and strength. The chemical’s capacity for pH regulation makes it invaluable in manufacturing and environmental management, while the food sector applies it carefully as a processing aid and pH buffer. Zenco Systems Ltd supplies Calcium Hydroxide Powder reliably in the region, supporting these interconnected markets with consistent product quality and supply chain expertise.
Calcium Hydroxide Powder's chemical identity is Ca(OH)₂, a compound formed by reacting calcium oxide (quicklime) with water in a process called slaking. This reaction produces a fine white powder composed primarily of hydrated calcium ions and hydroxide ions. Its molecular weight is 74.09 g/mol, and it exhibits slight solubility in water, producing a clear, strongly alkaline solution with a typical pH of around 12.4. This alkaline nature underpins much of its industrial value.
When dissolved, calcium hydroxide dissociates, releasing hydroxide ions that raise pH. This property allows it to neutralize acidic contaminants in water treatment, precipitate heavy metals, and adjust soil conditions in agriculture. The physical appearance as a fine white powder facilitates easy dosing and dispersion in liquids or mixes. Its caustic property necessitates careful handling, as the powder can irritate skin and eyes.
Performance in construction benefits from its moderate solubility and chemical reactivity, fostering chemical reactions that enhance mortar setting and durability. The compound also reacts with carbon dioxide in the atmosphere to form calcium carbonate, reinforcing hardened materials.
Purity and grade vary by application, ranging from technical grades for industrial pH control to food-grade for edible uses. Buyers sourcing from Zenco Systems Ltd should verify these specifications to fit exact process requirements. The compound's stability demands storage in dry, ventilated conditions to prevent hydration and caking, ensuring consistent performance.
Calcium Hydroxide Powder is widely used in municipal and industrial water treatment to raise pH, precipitate heavy metals, and remove suspended solids. Its alkaline solution neutralizes acidic contaminants and softens hard water by reacting with carbonate and bicarbonate ions. Dosages vary depending on water chemistry, but typical concentrations ensure effective coagulation and sedimentation, improving water clarity and safety.
In flue gas desulfurization (FGD), calcium hydroxide acts as a sorbent to capture sulfur dioxide emissions from power plants and factories. The powder, when hydrated and injected, reacts with SO₂ to form calcium sulfite or sulfate compounds, reducing atmospheric pollution and complying with environmental regulations. This chemical pathway is favored for its effectiveness and relatively low cost.
Slaked lime forms a core ingredient in mortars, plasters, and stucco. Its chemical reaction with carbon dioxide gradually converts it into calcium carbonate, providing strength and long-term durability to construction materials. It improves workability, adhesion, and water retention, making it a preferred binder in traditional and modern building practices across East Africa.
Calcium Hydroxide Powder is used to maintain or raise pH levels in various manufacturing streams, including chemical, paper, and mining industries. Its ability to create alkaline conditions enables control over precipitation, corrosion, and enzymatic processes, optimizing product quality and process efficiency. Dosage control is essential to avoid over-alkalinity that could harm equipment or downstream steps.
In the food industry, calcium hydroxide serves as a processing aid and pH regulator, particularly in the production of canned vegetables, sugar refining, and nixtamalization of maize. It assists in softening, sterilization, and flavor stabilization, while maintaining food safety standards. Only food-grade calcium hydroxide with confirmed purity is suitable for these applications.
Mining operations use calcium hydroxide to neutralize acidic mine drainage and adjust slurry pH to optimize metal recovery. It precipitates dissolved metals as insoluble hydroxides, aiding separation and reducing environmental impact. Precise dosing helps maintain process stability and complies with environmental discharge requirements.

Store Calcium Hydroxide Powder in a dry, cool, and well-ventilated area away from moisture sources, as it absorbs water and forms lumps upon hydration. Use airtight containers or sealed bags to maintain quality. Keep it segregated from acids, ammonium salts, and incompatible substances. Handling requires protective gloves, goggles, and dust masks since inhaling powder or skin contact can cause irritation. Shelf life is generally stable if stored properly but confirm stability periods with the certificate of analysis.
Calcium Hydroxide Powder is caustic and can cause skin and eye irritation upon contact. Always use gloves, protective eyewear, and dust masks during handling to avoid exposure. In case of contact, rinse affected areas with plenty of water immediately. Avoid inhaling dust; use adequate ventilation or respiratory protection. Dispose of waste according to local environmental regulations. Refer to the Safety Data Sheet (SDS) for complete hazard and first aid information.
It is primarily used for pH adjustment, water treatment to remove impurities, construction materials like mortar, food processing as a pH regulator, and environmental flue gas treatment.
Dosing depends on water acidity and contaminants, typically ranging from a few milligrams to several grams per litre, carefully adjusted to reach neutral or slightly alkaline pH without overdosing.
