What is the solubility of OEM Calcium Cyanamide in water?

As an OEM Calcium Cyanamide supplier, I often encounter questions from customers regarding the solubility of our product in water. This property is crucial as it directly impacts the product's applications in various industries, including agriculture, metallurgy, and chemical synthesis. In this blog post, I will delve into the solubility of OEM Calcium Cyanamide in water, exploring the factors that influence it and its implications for different uses.

Understanding OEM Calcium Cyanamide

Before discussing its solubility, let's briefly introduce OEM Calcium Cyanamide. OEM Calcium Cyanamide is a chemical compound with the formula CaCN₂. It is a grayish-black powder or granular material that is commonly used in agriculture as a fertilizer and in the chemical industry for the production of various nitrogen-containing compounds. Our company specializes in providing high-quality OEM Calcium Cyanamide, tailored to meet the specific needs of our customers.

Solubility of Calcium Cyanamide in Water

The solubility of Calcium Cyanamide in water is relatively low. At room temperature (around 25°C), the solubility of Calcium Cyanamide is approximately 1.2 g/L. This means that only a small amount of Calcium Cyanamide can dissolve in water under normal conditions. The low solubility is mainly due to the strong ionic bonds within the Calcium Cyanamide structure, which require a significant amount of energy to break and allow the compound to disperse in water.

However, the solubility of Calcium Cyanamide can be affected by several factors, including temperature, pH, and the presence of other substances.

Temperature

As with most chemical compounds, the solubility of Calcium Cyanamide in water increases with temperature. When the temperature rises, the kinetic energy of the water molecules increases, allowing them to more effectively break the ionic bonds in Calcium Cyanamide and dissolve it. For example, at 100°C, the solubility of Calcium Cyanamide can reach up to 2.5 g/L, which is more than twice its solubility at room temperature.

pH

The pH of the water also plays a crucial role in the solubility of Calcium Cyanamide. In acidic solutions, Calcium Cyanamide reacts with the hydrogen ions (H⁺) to form cyanamide (H₂NCN) and calcium ions (Ca²⁺). The reaction can be represented as follows:

CaCN₂ + 2H⁺ → H₂NCN + Ca²⁺

Cyanamide is more soluble in water than Calcium Cyanamide, so the solubility of Calcium Cyanamide increases in acidic solutions. On the other hand, in alkaline solutions, Calcium Cyanamide is relatively stable and its solubility remains low.

Presence of Other Substances

The presence of other substances in water can also affect the solubility of Calcium Cyanamide. For example, the addition of salts such as sodium chloride (NaCl) or calcium chloride (CaCl₂) can increase the ionic strength of the solution, which can either increase or decrease the solubility of Calcium Cyanamide depending on the specific salt and its concentration. Some organic compounds can also interact with Calcium Cyanamide and affect its solubility.

Implications of Solubility for Applications

Agriculture

In agriculture, Calcium Cyanamide is widely used as a fertilizer. Its low solubility in water allows it to be slowly released into the soil, providing a long-term source of nitrogen for plants. This slow-release property helps to prevent nitrogen leaching and ensures that the plants can absorb the nitrogen gradually over time. Additionally, the reaction of Calcium Cyanamide with water in the soil produces cyanamide, which has some fungicidal and insecticidal properties, helping to protect the plants from diseases and pests.

Chemical Industry

In the chemical industry, the solubility of Calcium Cyanamide is important for the production of various nitrogen-containing compounds. For example, Calcium Cyanamide can be used as a raw material for the synthesis of melamine, which is widely used in the production of plastics, adhesives, and coatings. The low solubility of Calcium Cyanamide can be an advantage in some processes, as it allows for better control of the reaction rate and product quality.

Metallurgy

In metallurgy, Calcium Cyanamide can be used as a reducing agent and a source of nitrogen. Its low solubility in water can be beneficial in some metallurgical processes, as it can prevent the loss of the compound due to dissolution in water-based solutions. For those interested in related metallurgical products, Calcium Carbide for Acetylene Production and Coal Carburetant are also important materials in the industry.

Conclusion

In conclusion, the solubility of OEM Calcium Cyanamide in water is relatively low under normal conditions, but it can be affected by temperature, pH, and the presence of other substances. Understanding the solubility of Calcium Cyanamide is crucial for its applications in agriculture, chemical industry, and metallurgy.
