Potassium aluminum silicate

Potassium aluminum silicate (CAS 1327-44-2), also known as potassium aluminium silicate, is a naturally occurring mineral compound sourced from aluminosilicate deposits and processed for industrial use.

It functions primarily as a carrier, filler, and functional additive across several manufacturing sectors. In printing and packaging, it is incorporated into coating formulations to improve ink adhesion.

This compound enhances surface uniformity on paper and board substrates. Water treatment operations use it as a coagulation aid and clarifying agent to remove suspended solids and turbidity from process water.

In oil and gas, it serves as a component in drilling fluid formulations where controlled viscosity and filtration properties are required. This ensures stability during complex extraction processes.

Pharmaceutical manufacturers use it as an excipient and carrier in solid dosage forms, supporting flow and compaction during tablet production. It is supplied as a fine white powder for these uses.

Particle size distributions are tailored to specific processing requirements. Technical and industrial grades are the most common supply forms, though pharmaceutical-grade material is also available.

Material meeting USP or Ph. Eur. specifications is available for regulated applications. Bulk and packaged formats are standard across the market to meet diverse industrial needs.
