Overview
High-stability active quicklime is a refined form of calcium oxide (CaO) engineered for consistent reactivity and reduced degradation during storage. Unlike traditional quicklime, it undergoes specialized calcination and stabilization processes to minimize premature slaking (reaction with moisture). This product is favored in industrial applications where controlled reactivity is critical, such as in steelmaking or flue gas desulfurization. Its 'active' designation refers to its rapid response to water, releasing heat and forming calcium hydroxide (slaked lime) for downstream processes.
Physical and Chemical Properties
The material exhibits a high melting point (2,572°C) and density (3.34 g/cm³), with a porous structure that enhances surface area for reactions. Its alkalinity (pH ~12.4 in slurry form) makes it effective for neutralizing acids. Key stability features include low free lime content and resistance to atmospheric carbonation, which reduces clumping during storage. Particle size distribution is tightly controlled, typically ranging from 1–100 μm for powdered grades.
Main Applications
In construction, it accelerates setting times in mortar and improves workability. Metallurgical uses include acting as a flux to remove impurities during steel production. Environmental applications dominate modern demand, particularly in wastewater pH adjustment and heavy metal precipitation. The agriculture sector employs it for soil pH correction and as a disinfectant in livestock housing.
Safety and Storage
Quicklime requires strict handling protocols due to its exothermic reaction with water. Storage silos must be climate-controlled with humidity below 50% to prevent unintended slaking. PPE mandates include chemical goggles, acid-resistant gloves, and dust masks. Spills should be contained with dry sand—never water—and disposed of as hazardous waste in many jurisdictions.
B2B Procurement Guide
Industrial buyers should prioritize suppliers with ISO 9001 certification for lime production. Key specifications to request: CaO content (≥92% for premium grades), reactivity time (measured by ASTM C110 slaking rate tests), and sieve analysis. Bulk purchases (20+ metric tons) often qualify for freight discounts. Consider regional availability—transportation costs may exceed material costs for remote locations due to weight.
