Product Characteristics and Use Considerations
Calcium hydroxide is an alkaline inorganic compound with the formula Ca(OH)₂. It is only slightly soluble in water, but the dissolved fraction provides alkalinity for pH adjustment and compatible neutralization or precipitation processes. Application dosage should be confirmed by process testing.
Applications
- Water and wastewater pH adjustment and compatible neutralization processes.
- Mining and mineral-processing applications requiring an alkaline lime source.
- Construction materials, mortar and related lime-based systems.
- Industrial chemical processing and environmental treatment applications.
How to Select the Right Grade
Confirm purity and its test basis, available calcium content, particle size, moisture, insoluble matter and the intended application. Water-treatment, mining and construction buyers may require different particle-size or impurity limits.
Packaging, Storage and Documents
Typical packaging is shown above and is confirmed by grade, quantity, transport requirements and destination. Store sealed and protected from moisture, and follow the applicable SDS, label and site procedures. TDS, MSDS/SDS and COA can be coordinated according to the confirmed grade, order and batch conditions.
Hydrated Lime Reactivity and Slurry Preparation
Calcium hydroxide grades with similar assay can behave differently in neutralization because particle size, available lime, carbonate content and slaking history affect dissolution and reactivity. The grade should be checked in the intended dosing system.
Key Purchasing Parameters
- Confirm Ca(OH)₂ or available-lime basis, moisture and calcium carbonate limits.
- Match particle size and flow behavior to dry feeding or slurry make-up equipment.
- Test neutralization rate, settling behavior and solids generation in the actual water.
- Specify bag, jumbo-bag or bulk handling requirements and dust-control provisions.
Related Products and Category
Compare sodium carbonate, potassium hydroxide, industrial alkalis as part of the wider process review; these products should not be treated as direct substitutes without application testing.
Information to Include in an Inquiry
Send the treatment duty, feed-water pH and flow, target pH, current lime dose, monthly volume, packaging and destination so reactivity and logistics can be reviewed together.
