Formula: SiO₂ 50/ZrSiO₄ 40/Al₂O₃ 10
Form: Rod
Material: Leachable Ceramic
Commodity: Ceramics
Leachable Ceramic Rod is engineered with controlled porosity and tailored dissolution behavior, making it ideal for creating internal cavities in advanced casting and molding processes. These rods exhibit high thermal stability and chemical resistance, enabling them to maintain structural integrity during metal casting or polymer molding before being selectively dissolved in leaching solutions. Industries such as metallurgy, aerospace, biomedical engineering, and advanced manufacturing employ these rods to produce complex internal geometries that cannot be machined directly. Specific uses include sacrificial cores in turbine blade production, precision casting of biomedical implants, and manufacturing of intricate heat-exchanger channels. Their controlled removal capability ensures accuracy and minimizes material stress, positioning them as crucial tools in design innovation. By enabling highly precise, lightweight, and structurally complex components, Leachable Ceramic Rod plays a central role in advancing both scientific research and industrial manufacturing efficiency.
