What is 4A Zeolite Powder CAS 1318-02-1?

4A Zeolite Powder CAS 1318-02-1 is a synthetic sodium aluminosilicate with an LTA framework and an effective pore opening of about 4 angstroms. It is also called Zeolite NaA, Sodium Zeolite A, or synthetic Zeolite A, and has EINECS number 215-283-8.

Why is 4A Zeolite Powder associated with CAS 1318-02-1 rather than 69912-79-4?

The title identifies this product as 4A Zeolite Powder. CAS 1318-02-1 is the standard registry number for Zeolite 4A / sodium aluminosilicate, while CAS 69912-79-4 is commonly used for calcium-exchanged 5A molecular sieve. Using the product-name-consistent CAS avoids mixing the 4A detergent grade with 5A molecular sieve.

What detergent-grade specifications matter most for 4A Zeolite Powder?

Key checks include calcium exchange capacity, high whiteness, 45 micron sieve residue, bulk density, loss on ignition, and pH. Typical detergent-grade material is a fine white powder with calcium exchange capacity around 295-315 mg CaCO3/g, whiteness above 95%, bulk density around 0.35-0.45 g/ml, and low oversize residue.

What non-detergent applications are suitable for 4A Zeolite Powder?

Outside detergent builders, Zeolite 4A is used as an adsorbent and desiccant, catalyst support or additive, wastewater and gas-treatment media, and in selected feed or soil-additive formulations. Its controlled pore size, ion-exchange activity, and thermal stability make it useful in these applications.

How should 4A Zeolite Powder CAS 1318-02-1 be stored?

Store it in closed bags or containers in a cool, dry, well-ventilated area away from direct sunlight and strong moisture. Keeping the product dry and protected from humidity helps preserve powder flow and reduces caking.

Product Description

4A Zeolite Powder CAS 1318-02-1 is a synthetic sodium aluminosilicate with an LTA framework and an effective pore opening of about 4 angstroms.

Synonyms: Zeolite NaA; Sodium Zeolite A; Synthetic Zeolite A; Sodium aluminosilicate 4A; LTA Zeolite Sodium.

CAS: 1318-02-1.

It has EINECS number 215-283-8; as an aluminosilicate, it has no fixed molecular formula.

It is a fine white, odorless powder.

It has a three-dimensional crystalline porous framework.

In wash water, its sodium ions exchange with calcium and, to a lesser extent, magnesium ions, which softens the water.

This allows surfactants to clean more effectively and makes it a phosphate-free detergent builder.

It is an environmentally preferred replacement for phosphate builders such as STPP.

A typical detergent-grade specification includes calcium exchange capacity of about 295–315 mg CaCO3/g.

It has high whiteness, typically above 95%, and bulk density around 0.35–0.45 g/ml.

It is used as an adsorbent, desiccant, catalyst support and additive.

It is used in wastewater and gas-treatment media and selected feed or soil-additive formulations.

Its controlled pore size, ion-exchange activity and thermal stability make it useful in these applications.

Confirm appearance, calcium exchange capacity, whiteness, sieve residue, bulk density, loss on ignition and pH.

Store in closed bags or containers in a cool, dry, well-ventilated area away from direct sunlight and strong moisture.

Confirm packaging with the requested quantity and destination requirements.
