—— The Preferred Calcium Source for Calcium Citrate Production, High Activity · Low Impurity · High Compatibility
Product Description
High-purity calcium oxide (commonly known as quicklime), with the molecular formula CaO, appears as white to slightly grayish white powder/granules, free of visible impurities and peculiar smell, with high whiteness and good fluidity. Processed by a special purification process, it strictly controls heavy metal content and has extremely high reaction activity and purity stability. As the core calcium source for calcium citrate production by the calcium salt method, this product can quickly react with water to form calcium hydroxide (lime milk), which then efficiently neutralizes with citric acid fermentation broth to generate high-purity calcium citrate precipitation. The entire reaction process is mild and highly controllable.
Core Advantages (Exclusive Characteristics for Calcium Citrate Production)
1. High Activity and Compatibility
This product has high activity (≥300ml), reacts quickly and completely with water, and can rapidly form uniform and fine lime milk without long-time stirring, greatly shortening the digestion reaction time in calcium citrate production. During the neutralization reaction, it combines closely with citric acid, with a conversion rate of over 98%, reducing calcium source waste and improving production efficiency.
2. High Purity and Low Impurity, Ensuring Product Quality
The main content is ≥98% with extremely low impurity content, avoiding impurities from being introduced into calcium citrate products, ensuring that the finished products meet the purity requirements of the food and pharmaceutical industries, and eliminating the need for additional deep purification processes.
3. High Cost-Effectiveness, Reducing Production Costs
Compared with other calcium sources such as calcium hydroxide and calcium carbonate, this product has higher activity and lower dosage, reducing the calcium source cost per unit output of calcium citrate by 15%-20%. At the same time, it produces less reaction residue, improves filtration and washing efficiency, reduces wastewater and waste residue treatment costs, and balances cost-effectiveness and environmental protection.
Notes
① This product is easy to absorb moisture and releases heat when in contact with water. It should be sealed and stored in a dry, ventilated and cool place, away from water sources and acidic substances to avoid caking.
② Protective equipment (gloves, masks, goggles) must be worn during operation to avoid direct contact with skin and respiratory tract. In case of accidental contact, rinse immediately with plenty of clean water.
③ When preparing lime milk, the water addition speed should be controlled to avoid splashing caused by local overheating, and stir evenly to ensure complete digestion.
④ It is recommended to test the activity and purity of this product before use to ensure it matches the production requirements.

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.
