Sodium sulfate(Cas 7757-82-6) Usage
| Description |
Sodium sulfate (Na₂SO₄), also known as disodium sulfate or sulfate of soda, is a white crystalline solid that is highly soluble in water. It is a versatile inorganic compound used extensively across various industries. |
| Production Methods |
Sodium sulfate can be derived from two main sources:
Natural Sources: Extracted from naturally occurring brines or crystalline evaporite deposits.
Chemical Byproduct: Produced as a byproduct of chemical processes such as acid recycling in the battery industry.
|
| Uses |
Detergents and Soaps: Used as a filler in powdered laundry detergents due to its high solubility and low cost.
Glass Manufacturing: Functions as a fining agent to remove small air bubbles from molten glass.
Textile Industry: Plays a role in dyeing textiles, helping to even out dye penetration.
Alkali Activation Processes: Sodium sulfate is an eco-friendly activator for alkali-activated composites (AACs) and geopolymers. It plays a key role in binding properties of alternative binders to Ordinary Portland Cement (OPC).
|
| Hazards and Safety |
Toxicity: Sodium sulfate is generally non-toxic but can cause eye and skin irritation upon contact. It is considered safe for general industrial and pharmaceutical uses but should still be handled carefully to avoid accidental exposure.
Environmental Considerations: While not highly hazardous, sodium sulfate is considered an environmental contaminant if released in large quantities due to its high solubility and potential effects on water ecosystems. |
| Physiological Function as a Laxative |
Sodium sulfate works as an osmotic laxative by increasing the retention of water in the intestines, softening stool, and promoting bowel movement. This effect makes it valuable in bowel preparations before medical procedures like colonoscopies. |

Data from the environmental scanning electron microscope (ESEM) show no hydration phenomena following wetting of thenardite; instead, thenardite dissolution occurs, followed by thenardite plus mirabilite crystallization upon drying. These results offer new insight into how damage is caused by sodium sulfate in natural geological, archaeological, construction and engineering contexts. They also help explain some of the controversial results of various commonly used sodium sulfate crystallization tests.

For example, the use of SS has been found to yield lower workability and higher shrinkage thereby making AACs made with such activator(s) suitable for specific applications where higher workability and lower shrinkage are required. On the other hand, the evolution of AACs over the years has shown that alternative sustainable and cheaper alkali activators can be used as a replacement for the conventional ones. Some of the alternative activators for AAC are sodium carbonate (SC), lime (LM), and sodium sulfate (SST). The low alkalinity of these alternative activators compared to the conventional ones makes their utilization on a large scale more practical and safer.
