Calcium Oxide (CaO), commonly known as quicklime, is a high-purity inorganic alkaline compound. It appears as a white or off-white powder/granule with strong hygroscopicity and alkaline reactivity. Produced from high-quality limestone through high-temperature calcination, this product features low impurity content and high reactivity. It is widely used in the production of calcium-based fertilizers, soil improvement, chemical synthesis, environmental treatment, and other fields, serving as an excellent raw material for manufacturing calcium fertilizers and compound fertilizers.
Core Application: For Calcium-Based Fertilizer Production
1. Raw Material for Calcium Fertilizers
Serves as the main source of calcium for the production of quicklime calcium fertilizer, calcium magnesium fertilizer, alkaline calcium-based compound fertilizer, soil conditioners, etc.
Supplements essential calcium nutrition for crops, improves fruit hardness, reduces cracking, and enhances plant stress resistance.
2. Soil Improvement and pH Adjustment
Neutralizes soil acidity, improves the structure of acidic soil, and increases soil permeability.
Adjusts soil pH, promotes beneficial microbial activity, and improves fertilizer utilization efficiency.
3. Sterilization, Pest Control and Soil Purification
Inhibits the growth of soil-borne diseases, underground pests and nematodes through its alkaline properties.
Reduces continuous cropping obstacles and creates a healthy soil environment for crop growth.

Our Advantages
We have our own mine in Hubei Province, which endows us with the following advantages:
Stable Raw Material Supply: Owning our own mine ensures a stable supply of raw materials for calcified substances. This helps to avoid production interruptions caused by issues such as fluctuations in the raw material market and supply shortages. It guarantees the smooth progress of production plans and maintains a stable product output, enabling us to better meet customer needs and enhance customer satisfaction.
Controllable Raw Material Quality: Our company can directly manage and monitor the mining process of the mine, and strictly control the quality of raw materials. We are able to select appropriate ore grades and qualities according to production requirements, ensuring that the mined ore meets the high standards of our products. This provides a solid foundation for producing high-quality calcified substance products and helps to enhance the market competitiveness of our products.
Cost Advantage: Obtaining raw materials from our own mine reduces intermediate procurement links and lowers procurement costs. Moreover, in the long run, a stable raw material supply also enables our company to take the initiative in cost control and avoid the risk of cost increases due to fluctuations in raw material prices, thereby improving the company's economic benefits and profitability.
