Applications of Calcium Sodium Aluminosilicate

1. Food & Beverage Industry

Calcium sodium aluminosilicate is widely used as a food-grade anti-caking agent. It prevents powdered ingredients from clumping, maintains free-flowing properties, and enhances product stability. Common applications include table salt, powdered dairy products, baking mixes, and instant beverage powders, ensuring consistent quality during storage and handling.

2. Chemical & Petrochemical Industry

In the chemical sector, it functions as a catalyst, adsorbent, and ion-exchange material. Its unique porous structure allows for efficient adsorption of gases, moisture, and organic vapors, while serving as a support for catalysts. It is essential in fine chemical synthesis, industrial gas purification, and petrochemical refining.

3. Coatings, Paints & Inks

It serves as a functional filler and performance modifier in coatings and paints. It enhances rheology, provides matting effects, improves dispersion, and prevents settling. These properties contribute to smoother surfaces, improved durability, and uniform appearance in coatings and inks.

4. Plastics & Rubber

Calcium sodium aluminosilicate acts as a reinforcing filler in plastics and rubber, improving mechanical strength, thermal resistance, and dimensional stability. It also enhances processing flowability, anti-blocking properties, and surface finish in materials such as PVC, PE films, rubber compounds, and engineering plastics.

5. Pharmaceutical & Nutraceutical Applications

Used as an excipient in tablets and capsules, it improves powder flow, uniform mixing, compressibility, and moisture resistance. This ensures consistent dosage, high manufacturing efficiency, and superior product quality for vitamins, minerals, and medicinal formulations.

6. Animal Feed Industry

It functions as an anti-caking and flow-enhancing agent in feed premixes and additives. Its moisture-absorbing properties maintain feed stability, prevent clumping, and improve handling efficiency during production and storage.

7. Ceramics & Glass Manufacturing

Calcium sodium aluminosilicate improves sintering behavior, structural stability, and texture control in ceramic and glass products. Its thermal stability and chemical inertness make it ideal for high-temperature processing, ensuring consistent quality and durability.

Key Features of Calcium Sodium Aluminosilicate (CAS 1344-02-1)

1. Excellent Chemical Stability

Calcium sodium aluminosilicate is highly chemically stable and insoluble in water, ethanol, and most dilute acids (except hydrofluoric acid) at room temperature. It exhibits a broad range of acid and alkali resistance (stable from pH 2 to 12), does not decompose or volatilize at high temperatures below 800℃, and remains inert with most organic materials such as plastics, oils, and fragrances. These properties make it ideal for high-temperature processing, strong acid formulations, and complex industrial applications.

2. Strong Adsorption and Dispersion Capabilities

This synthetic amorphous aluminosilicate has a highly porous structure with a specific surface area of 100–300 m²/g, enabling it to adsorb 10–30% of its own weight in water or oil. It can be uniformly dispersed in liquid or powder systems, effectively preventing particle agglomeration, caking in food powders, or pigment sedimentation in coatings, ensuring stable product performance and enhanced processability.

3. High Safety and Biocompatibility

Calcium sodium aluminosilicate is certified for safety by multiple authorities, including China’s GB 2760, the US FDA GRAS, and the EU EFSA. It has extremely low oral toxicity (LD₅₀ > 10 g/kg in rats), is not absorbed by the human body, and is excreted naturally. Additionally, it does not cause skin sensitization, making it suitable for use in food, feed, and daily chemical products, including formulations intended for infants and young children.
