Description

Potassium Trialuminum Trisilicon Decaoxide Dihydroxide is a specialized aluminosilicate compound, also known as a potassium-exchanged zeolite or synthetic mica. This engineered material is valued for its unique ion-exchange capacity, thermal stability, and layered structure, making it a critical functional additive in advanced industrial processes. It is primarily utilized by manufacturers in the ceramics, catalyst, and polymer composite industries seeking to enhance material properties such as strength, flame retardancy, and thermal insulation.

Application

• Catalyst & Catalyst Support: Used as a solid acid catalyst or support material in petroleum refining and chemical synthesis due to its stable framework and ion-exchange sites.
• Advanced Ceramics & Refractories: Acts as a fluxing agent and reinforcing filler to improve the sintering behavior, mechanical strength, and thermal shock resistance of high-performance ceramics.
• Polymer Composites: Incorporated as a functional filler in engineering plastics and elastomers to enhance flame retardancy, reduce smoke emission, and improve dimensional stability.
• Inorganic Pigments & Coatings: Serves as a carrier or stabilizer for inorganic pigments, improving their dispersion and weather resistance in high-temperature coatings.
• Molecular Sieves & Adsorbents: Employed in selective adsorption processes for gas separation or purification, leveraging its controlled pore structure.
• Glass & Enamel Frits: Used as a source of alumina, silica, and potassium to modify the viscosity, chemical durability, and optical properties of specialty glasses and enamel coatings.

Quality Control

Our production of Potassium Trialuminum Trisilicon Decaoxide Dihydroxide adheres to stringent quality management protocols. Each batch is characterized for critical parameters including chemical composition, crystalline phase, particle size distribution, and ion-exchange capacity to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption and caking. Separate from strong acids and fluorides.
