pH-stable ceramics (pH-stabilizing ceramics) are ceramic materials designed to maintain the hydrogen ion concentration (pH) in water within a specific range, typically from slightly alkaline to near neutral. They are primarily used as filter media for ornamental fish tanks and as filtration elements in water purifiers, and are employed to prevent sudden fluctuations in water quality. Features and Applications Water Quality Stabilization (Ornamental Fish/Aquariums) Ring filter media, which prevents the water in the aquarium from becoming acidic and stabilizes it near neutral, are common. Porous ceramics with a large surface area for bacteria to colonize are used, combining filtration and pH adjustment functions. High Corrosion Resistance and Acid Resistance Generally, ceramics are resistant to acids and alkalis and are chemically stable, ensuring stable quality even after long-term use. Thank you for viewing.
