Highly Porous Open Cell Zinc Foam
Introdução
- Zinc Foam is an open‑cell porous zinc metal with a 3D interconnected structure and high porosity, providing a large specific surface area and low density. Manufactured from high‑purity zinc (typically ≥99.9%), it offers good electrical conductivity and excellent electrolyte penetration, making it ideal as an anode or current collector in zinc‑ion batteries, alkaline batteries, electroplating systems and other electrochemical applications.
- With uniform pore distribution and stable mechanical strength, Zinc Foam enhances mass transfer and reaction efficiency for electrodes and catalytic layers. It is widely used as a catalyst support, in fuel cells, sensors, corrosion‑protection components, gas diffusion layers, filtration and lightweight conductive structures. The foam can be supplied in sheets or custom‑cut parts with adjustable thickness, pore size (PPI) and density according to customer requirements.
Especificações
| Tipo | Open cell zinc metal foam |
| Pureza | Zn ≥ 99.9% (high‑purity zinc; other grades on request) |
| Formulário | Sheet, roll, or custom‑cut blocks/parts depending on size & thickness |
| Tamanho da célula (PPI) | Typically 10–80 PPI; other pore sizes can be customized |
| Espessura | Standard: approx. 0.5–20 mm; other thicknesses can be customized |
| Tamanho e forma | Common sheets: e.g. 100 × 100 mm / 200 × 300 mm; can be cut or made into different shapes as per request |
| Porosidade | Typically about 70% – 97%, depending on grade and PPI |
| Taxa de células abertas | Usually ≥ 95% (most cells interconnected) |
| Densidade volumétrica | Approx. 0.2–1.0 g/cm³ (adjustable by porosity and structure) |
| Densidade superficial | Approx. 100–4000 g/m², depending on thickness and density |
| Thermal Conductivity (Effective) | Typically around 1–20 W/m·K (strongly depends on porosity; bulk zinc ~ 116 W/m·K) |
| Mechanical Strength (Compressive) | Typically about 1–5 MPa (varies with density and pore size) |
| Average Tensile Strength (N/20 mm) | Vertical ≥ 15, horizontal ≥ 10 (typical for thin, flexible foam strips; can vary with product) |
| Temperature Resistance (Inert Atmosphere / Vacuum) | Generally ≥ 350–400 ℃ for long‑term use (zinc melting point ~419.5 ℃; actual usable temperature depends on application and environment) |
| Aparência | Metallic silver‑gray zinc, uniform color, without obvious defects such as heavy oxidation spots, blind holes, through holes, large cracks, etc. |
| Chemical Composition | Zn ≥ 99.9%; typical metallic impurities (Pb, Cd, Fe, Cu, etc.) each usually ≤ 0.05% (exact limits depend on grade/standard) |
| Electrical Conductivity | Good electrical conductivity; bulk zinc resistivity ~5.9 × 10⁻⁸ Ω·m (effective value decreases with porosity and foam structure) |
| Corrosion Resistance | Good corrosion resistance in many neutral and mildly alkaline environments; sacrificial anode behavior in some systems; not suitable for strong acids, strong oxidizing media or environments where zinc dissolution is undesirable |
| Flexibilidade | Certain flexibility for thin, low‑density sheets; can be bent and slightly compressed, but brittleness increases with thickness and low porosity |
| Elongation Rate (%) | Typically low elongation compared with ductile metals; for thin, high‑porosity foam, vertical ≈ 2–4%, horizontal ≈ 3–5% (reference values) |
| Aplicações | Battery anodes and current collectors (zinc‑ion, alkaline batteries), electrocatalyst supports, electroplating and corrosion‑protection electrodes, fuel cell and electrochemical components, filtration, gas diffusion media, sound absorption, heat dissipation and lightweight structural parts requiring conductive porous zinc material |
