Sodium Alumina Silicate

Whatsapp Order

Sodium Alumina Silicate is an inorganic compound consisting of sodium, aluminum, and silicon oxides. It is typically found as a white, amorphous powder with excellent adsorption and ion-exchange properties. Commonly used as a detergent builder, water softener, and desiccant, sodium alumina silicate improves cleaning efficiency, controls water hardness, and aids moisture absorption. Its thermal stability and chemical inertness make it valuable across detergent manufacturing, water treatment, and various industrial processes.

Description

Uses

Primary Uses

Detergents and Cleaning Products

Acts as a builder in laundry detergents to soften water by binding calcium and magnesium ions.
Enhances cleaning efficiency by improving surfactant performance.
Used in automatic dishwasher powders to prevent scale formation and enhance cleaning.

Water Treatment

Utilized in water softening systems to remove hardness ions.
Employed in industrial wastewater treatment for ion exchange and removal of heavy metals.

Desiccants and Moisture Absorption

Used as a desiccant in packaging to control moisture and prevent product degradation.

Construction Industry

Added as a filler or functional additive in cement and concrete formulations to improve durability and reduce porosity.

Secondary Uses

Catalyst Support

Used as a support material in heterogeneous catalysis due to its thermal stability and surface properties.

Ceramics and Glass Manufacturing

Serves as a raw material or additive to modify the properties of ceramic and glass products.

Agriculture

Occasionally used as a carrier or additive in fertilizers and soil conditioners.
