Highly active calcium oxide is finely calcined from premium raw materials, featuring high purity, strong activity and low impurity content. With uniform texture, it reacts rapidly and completely with water, delivers fast slaking speed, strong alkalinity and excellent adsorption capacity, while maintaining stable chemical properties.

Compared with ordinary calcium oxide, this product offers higher reaction efficiency, lower dosage, fast sedimentation and superior impurity removal. It resists caking and is convenient for storage and application. Widely used in flue gas desulfurization, industrial wastewater treatment, acid-base neutralization, metallurgy, chemical industry, building materials, soil improvement and environmental purification. With stable and reliable quality, it serves as an ideal basic raw material for industrial production and environmental protection treatment.

Own mines in Hubei

Leveraging the superior resource endowment of our own mines in Hubei, the quicklime we produce demonstrates remarkable quality advantages: not only does its effective calcium oxide content far exceed the industry average, but its extremely low impurity ratio also ensures high-performance in applications. The mine resources, which are controlled from the source, endow the quicklime with a natural purity base. Coupled with sophisticated calcination technology, each batch of products can maintain stable high activity — this not only provides solid support for efficient slag formation and deep impurity removal in iron and steel smelting, but also meets the stringent requirements for high-quality quicklime in fields such as construction and chemical industry.
