CarboCore supplies quicklime for steel production, flue gas treatment, water purification, and chemical manufacturing.
Quicklime begins with geology, but its value is proven in production. Egypt's quicklime starts as high-calcium limestone from ancient seabeds, burned above 900 °C to drive off carbon dioxide and leave highly reactive calcium oxide. Origin alone does not decide performance. Available CaO, reactivity, residual CO₂ and particle size do. That is where every CarboCore order begins.
Applications are indicative and subject to the selected grade’s chemical composition, particle-size distribution, surface treatment and processing characteristics. CarboCore’s technical team supports customers in selecting the appropriate grade for their formulation and manufacturing process.
Food, feed, pharmaceutical, cosmetic, medical and potable-water applications require separately evaluated and approved grades. Compliance should not be claimed unless the relevant certification and regulatory documentation are available.

Quicklime causes serious eye damage and skin irritation. Handle with eye and skin protection as described in the SDS.
Values are typical reference data for Egyptian quicklime supplied by CarboCore and are intended for buyer screening. Final specifications, reactivity, size and suitability are confirmed per grade, application and shipment lot on the certificate of analysis. Samples are available on request.
The final specification should establish:
Report separately using identified test methods.
Define slaking time or temperature rise under agreed test conditions.
Establish limits to assess material condition.
Specify the size range, fines, and oversize limits.
Confirm MgO, SiO₂, Al₂O₃, Fe₂O₃, and application-specific requirements.
Request the Technical Data Sheet (TDS), Safety Data Sheet (SDS), and batch-specific Certificate of Analysis (COA).
Technical approval should establish composition, available lime, reactivity, and sizing. Batch documentation should distinguish measured results from guaranteed acceptance limits.

Packaging options include 25 kg bags, 1,000 kg jumbo bags, and bulk silo supply. Final packaging, loading quantities, and shipment arrangements are confirmed in the quotation.
Quicklime reacts with water to form hydrated lime and releases substantial heat. Keep tightly protected from water and humidity at all times. Storage and handling must follow the product SDS.
