Highly Porous Open Cell GOLD FOAM
مقدمة
- GOLD FOAM is an open‑cell metallic gold foam with high porosity (typically 70–98%) and a purity up to 99.99% Au. The 3D interconnected pore structure provides a very large surface area, excellent electrical conductivity and good thermal performance, making it ideal as a current collector or substrate for electrocatalysts, fuel cells, sensors and high‑performance battery electrodes. Standard formats include sheets and rolls with customizable thickness, PPI and density according to your application.
- With uniform cell size, stable mechanical strength and outstanding corrosion resistance, GOLD FOAM maintains conductivity and structural integrity even in harsh chemical environments. It can be easily cut, punched and shaped into different sizes, and is widely used in electrochemical research, hydrogen evolution/oxygen evolution reactions, EMC/EMI shielding components, precision filtration and high‑end decorative or luxury craft projects that require a real metallic gold appearance.
