QUICK LIME POWDER

Quick Lime Powder (Calcium Oxide – CaO)
Other names: Burnt Lime Powder, Calcined Lime Powder, Unslaked Lime Powder
Manufacturer: Vietnam Technology Mineral JSC

Description:
Quick Lime Powder is a finely ground form of calcium oxide, produced by calcining high-quality limestone (CaCO₃) in rotary kilns at high temperatures. During this process, carbon dioxide (CO₂) is released, leaving pure CaO:
Reaction: CaCO₃ → CaO + CO₂

The powder form offers larger surface area and faster reactivity compared to quick lime lumps, making it ideal for applications that require rapid chemical reactions and homogeneous mixing. When in contact with water, it reacts vigorously (slaking), generating intense heat. With an alkaline pH around 12.5, it is strongly caustic — strict safety measures are required during handling.

Key Specifications:

• CaO content: ≥ 90% (premium-grade)

• Particle size: 200 mesh

• Moisture content: ≤ 1–2% to maintain maximum reactivity

• Impurities: MgO ≤ 2.5%; negligible heavy metals (Pb, As)

• Reactivity: Extremely fast slaking, ideal setting time ~24 hours

• Consistency: Uniform fineness, purity, and burning degree across batches

• Storage stability: Retains quality for 6–12 months if stored in dry, airtight conditions

• Source traceability: Produced from selected limestone and controlled kiln operations

Applications:
Quick Lime Powder is suitable for a wide range of industries:

• Metallurgy: Flux in steel refining and non-ferrous metal processing

• Construction: Accelerated setting in mortars and plasters, soil stabilization

• Water Treatment: Rapid pH adjustment, softening, and contaminant removal

• Chemical Manufacturing: Calcium carbide, soda ash, bleaching powder production

• Paper & Pulp: Causticizing and pulp digestion in kraft process

• Environmental Protection: Flue gas desulfurization, neutralization of acidic waste

• Agriculture: Soil amendment, pest control, livestock odor reduction

Production Advantage:
Produced in modern rotary kilns and finely milled for consistent quality, high reactivity, and optimal performance in demanding applications.
