What are the quality standards for Sodium Metaaluminate (11138 - 49 - 1)?
Jun 18, 2025
As a supplier of Sodium Metaaluminate (CAS No. 11138 - 49 - 1), I've had numerous discussions with clients regarding the quality standards of this essential chemical compound. Sodium Metaaluminate is widely used in various industries, including water treatment, paper manufacturing, and the production of white carbon black. Understanding its quality standards is crucial for both producers and end - users to ensure optimal performance and compliance with industry regulations.
Chemical Composition
The first and most fundamental aspect of the quality standards for Sodium Metaaluminate is its chemical composition. Pure Sodium Metaaluminate has the chemical formula NaAlO₂. However, in commercial products, it often exists in different forms, such as a solid or a liquid solution.
The purity of Sodium Metaaluminate is a key indicator of its quality. High - purity Sodium Metaaluminate typically contains a high percentage of NaAlO₂, with minimal impurities. Impurities can include other metal salts, such as iron, calcium, and magnesium salts, as well as insoluble particles. These impurities can have a negative impact on the performance of Sodium Metaaluminate in various applications. For example, in water treatment, iron impurities can cause discoloration of the treated water, while insoluble particles can clog filters.
In the case of liquid Sodium Metaaluminate, the concentration of the solution is also an important factor. A common concentration is 37%, which offers a good balance between reactivity and ease of handling.

Physical Properties
Physical properties also play a significant role in determining the quality of Sodium Metaaluminate. These properties include appearance, density, and viscosity.
The appearance of Sodium Metaaluminate can vary depending on its form. Solid Sodium Metaaluminate is usually a white or off - white powder or granular material. Any signs of discoloration, such as yellowing or darkening, may indicate the presence of impurities or degradation. Liquid Sodium Metaaluminate should be clear and free of any visible particles or sediment.
Density is an important physical property, especially for liquid Sodium Metaaluminate. The density of a Sodium Metaaluminate solution is related to its concentration. A higher - density solution generally indicates a higher concentration of NaAlO₂. Viscosity is another property that can affect the handling and application of liquid Sodium Metaaluminate. A solution with too high a viscosity may be difficult to pump and mix, while a solution with too low a viscosity may not have the desired reactivity.
Chemical Reactivity
The chemical reactivity of Sodium Metaaluminate is a critical quality parameter. In water treatment, Sodium Metaaluminate is used as a coagulant aid. It reacts with water to form aluminum hydroxide, which helps to remove suspended solids and impurities from the water. The reactivity of Sodium Metaaluminate can be affected by its purity, concentration, and the presence of impurities.
In the production of white carbon black, Sodium Metaaluminate is used as a reactant. It reacts with silica to form a gel - like substance, which is then processed to produce white carbon black. The quality of Sodium Metaaluminate can significantly affect the quality of the final product. You can find more information about Sodium Metaaluminate for White Carbon Black on our website.
Industry Standards and Regulations
There are several industry standards and regulations that govern the quality of Sodium Metaaluminate. These standards ensure that the product meets the requirements of different applications and is safe for use.
In the water treatment industry, Sodium Metaaluminate must comply with the standards set by regulatory bodies such as the Environmental Protection Agency (EPA). These standards specify the maximum allowable levels of impurities, such as heavy metals, in the product. In addition, the product must be labeled correctly to provide information about its composition, concentration, and safety precautions.
In the chemical manufacturing industry, Sodium Metaaluminate must meet the quality requirements of the end - users. For example, in the production of paper, the quality of Sodium Metaaluminate can affect the strength and whiteness of the paper. Therefore, paper manufacturers often have their own strict quality standards for Sodium Metaaluminate.
Quality Control in Production
As a supplier, we implement strict quality control measures throughout the production process to ensure that our Sodium Metaaluminate meets the highest quality standards.
We start with high - quality raw materials and carefully control the reaction conditions during the production process. This helps to ensure the purity and consistency of the final product. After production, we conduct a series of tests on the product, including chemical analysis, physical property testing, and reactivity testing. These tests help us to identify any potential quality issues and take corrective actions before the product is shipped to our customers.
Importance of Quality for Customers
For our customers, using high - quality Sodium Metaaluminate is essential for the success of their operations. In water treatment, high - quality Sodium Metaaluminate can improve the efficiency of the treatment process, reduce the amount of chemicals needed, and produce cleaner water. In the paper manufacturing industry, it can improve the quality of the paper and reduce production costs.
In addition, using high - quality Sodium Metaaluminate can also help our customers to comply with industry regulations and avoid potential legal issues. By ensuring that the product meets the required quality standards, we can help our customers to maintain a good reputation in the market.
Conclusion
In conclusion, the quality standards for Sodium Metaaluminate (11138 - 49 - 1) are determined by a combination of factors, including chemical composition, physical properties, chemical reactivity, and industry standards. As a supplier, we are committed to providing high - quality Sodium Metaaluminate that meets the diverse needs of our customers.
