What are the storage conditions for liquid sodium aluminate?
Jun 03, 2025
Liquid sodium aluminate is a versatile chemical compound widely used in various industries, including water treatment, pulp and paper, and construction. As a trusted supplier of liquid sodium aluminate, we understand the importance of proper storage conditions to maintain its quality and effectiveness. In this blog post, we will discuss the essential storage conditions for liquid sodium aluminate and provide some useful tips to ensure its long-term stability.
Chemical Properties of Liquid Sodium Aluminate
Before delving into the storage conditions, it is crucial to understand the chemical properties of liquid sodium aluminate. Liquid sodium aluminate is an aqueous solution of sodium aluminate, which is a white crystalline solid. The chemical formula of sodium aluminate is NaAlO₂, and it is highly soluble in water. The solution is alkaline, with a pH typically ranging from 11 to 13, and it can react with acids to form salts and water.
Temperature
One of the most critical factors in storing liquid sodium aluminate is temperature. The ideal storage temperature for liquid sodium aluminate is between 5°C and 35°C (41°F and 95°F). At temperatures below 5°C, the solution may start to crystallize, which can lead to clogging of pipes and equipment. On the other hand, at temperatures above 35°C, the solution may decompose, resulting in a loss of its chemical properties and effectiveness.
It is essential to store liquid sodium aluminate in a temperature-controlled environment, such as a warehouse or storage tank with proper insulation. If the storage area is exposed to extreme temperatures, it may be necessary to use heating or cooling systems to maintain the optimal temperature range.
Humidity
Humidity can also affect the quality of liquid sodium aluminate. High humidity levels can cause the solution to absorb moisture from the air, which can dilute the solution and reduce its concentration. This can lead to a decrease in its effectiveness and may require additional product to achieve the desired results.


To prevent moisture absorption, it is recommended to store liquid sodium aluminate in a dry environment with a relative humidity of less than 70%. If the storage area is prone to high humidity, it may be necessary to use dehumidifiers or moisture barriers to maintain the appropriate humidity levels.
Container Material
The choice of container material is another important consideration when storing liquid sodium aluminate. The solution is highly alkaline and can react with certain metals, such as aluminum, copper, and zinc, which can cause corrosion and contamination of the solution. Therefore, it is recommended to store liquid sodium aluminate in containers made of materials that are resistant to alkaline solutions, such as polyethylene, polypropylene, or fiberglass-reinforced plastic (FRP).
It is also important to ensure that the containers are clean and free of any contaminants before filling them with liquid sodium aluminate. This can help prevent the growth of bacteria or other microorganisms, which can affect the quality of the solution.
Ventilation
Proper ventilation is essential when storing liquid sodium aluminate. The solution can release ammonia gas, which is toxic and can cause respiratory problems if inhaled in high concentrations. Therefore, it is recommended to store liquid sodium aluminate in a well-ventilated area to prevent the accumulation of ammonia gas.
If the storage area is enclosed, it may be necessary to install ventilation systems, such as exhaust fans or air purifiers, to ensure adequate air circulation. It is also important to monitor the ammonia gas levels regularly to ensure that they are within the safe limits.
Handling and Transfer
When handling and transferring liquid sodium aluminate, it is important to follow proper safety procedures to prevent spills and accidents. The solution is highly corrosive and can cause severe burns if it comes into contact with the skin or eyes. Therefore, it is recommended to wear appropriate personal protective equipment (PPE), such as gloves, goggles, and protective clothing, when handling the solution.
It is also important to use proper equipment, such as pumps, hoses, and valves, that are compatible with the solution. The equipment should be regularly inspected and maintained to ensure its proper functioning and to prevent leaks and spills.
Storage Duration
The storage duration of liquid sodium aluminate can also affect its quality and effectiveness. Over time, the solution may start to degrade, resulting in a loss of its chemical properties and effectiveness. Therefore, it is recommended to use the solution within six months of its production date to ensure its optimal performance.
If the solution has been stored for an extended period, it is recommended to test its quality before using it. This can help ensure that the solution is still effective and meets the required specifications.
Tips for Long-Term Storage
To ensure the long-term stability of liquid sodium aluminate, here are some additional tips:
- Regularly inspect the containers: Check the containers for any signs of damage, such as cracks, leaks, or corrosion. If any damage is detected, the solution should be transferred to a new container immediately.
- Monitor the solution levels: Keep track of the solution levels in the containers to ensure that they are not overfilled or underfilled. Overfilling can cause spills and accidents, while underfilling can lead to air pockets, which can promote the growth of bacteria and other microorganisms.
- Rotate the stock: If you have multiple containers of liquid sodium aluminate, it is recommended to rotate the stock to ensure that the oldest solution is used first. This can help prevent the solution from expiring and ensure its optimal performance.
- Keep records: Maintain detailed records of the storage conditions, including the temperature, humidity, and storage duration, as well as the date of receipt and the batch number of the solution. This can help you track the quality of the solution and ensure that it is used within the recommended time frame.
