Properties common to all products in this list

Composition: KAl₂(AlSi₃O₁₀)(F,OH)₂ Form: Disk Material: Potassium Aluminosilicate CAS Number: 1327-44-2 Commodity: Ceramics Color: Clear Ruby
Potassium Aluminosilicate Disk provides high thermal stability, ion-exchange capacity, and mechanical strength in a precisely machined circular format. With excellent resistance to alkali corrosion and shape-selective adsorption, it is employed in catalysis, water purification, and structural ceramics. Industries such as energy, environmental engineering, and chemical processing use potassium aluminosilicate disks in furnace linings, ion-exchange filters, and catalyst substrates. Specific applications include water softening media, refractory components in high-temperature reactors, and carrier substrates for catalytic coatings. Research explores its structural stability under alkali load, NMR characterization of ion exchange processes, and its potential as recyclable refractory material. The disk geometry ensures reproducibility in electrochemical and adsorption tests, while its chemical durability makes it suitable for harsh environments. Its unique balance of functionality and structural resilience positions it as a key material bridging industrial applications and advanced materials research.
