Ceramic Balls are spherical media produced by sintering high-quality inorganic non-metallic materials like kaolin at high temperatures. They boast high mechanical strength, excellent chemical resistance, and good biocompatibility. Our Chinese Ceramic Balls feature a smooth surface with a controlled microporous structure. This makes them ideal as high-efficiency bio-filter media for microbial colonization in water treatment and aquaculture, and as functional fillers to adjust soil physical properties. In high-end horticulture, they are often used as support media in hydroponic or aeroponic systems. Their chemical stability ensures they won't decompose or release harmful substances over time, making them a high-tech, long-lasting cultivation aid.
