Nickel Foam 99% Ni 40 PPI Open Cell Packing ATOMFAIR®

NICKEL FOAM 99% NI 40 PPI OPEN CELL DISTILLATION PACKING MATERIAL

RESEARCH GRADE MATERIAL

Product Overview

This high-purity Nickel Foam substrate features a 99% nickel 40 PPI open cell architecture manufactured via a plain-weave electrodeposition process, delivering exceptional structural uniformity and chemical purity for demanding laboratory and industrial applications. With a through-hole ratio exceeding 98% and porosity ranging from 60–70%, the material provides superior fluid permeability and an extensive specific surface area ideal for distillation column packing material and vapor-liquid mass transfer operations. The intrinsic acid-alkali corrosion resistant properties of nickel—reinforced by a dense passivating oxide film formed at ambient temperature—ensure long-term chemical stability against organic acids, alkaline solutions, and oxidizing environments. Capable of withstanding continuous operating temperatures above 500°C with a thermal conductivity exceeding 3 W/(m²·K), this foam serves as a versatile platform for catalysis, electrochemical energy storage, and high-temperature filtration across academic research and industrial R&D settings.

Key Features & Advantages

Ultra-High Purity Nickel (Ni > 99%): The elemental composition exceeds 99% nickel with only trace carbon and chemical deposits, ensuring minimal catalytic interference and superior electrochemical stability for sensitive electrode and catalyst carrier applications where material purity directly governs experimental reproducibility.
Self-Passivating Corrosion Barrier: Nickel forms a dense, adherent oxide film spontaneously at ambient temperature, conferring intrinsic resistance to organic acids, alkaline solutions, and atmospheric oxidation. Concentrated nitric acid further passivates the surface, enhancing anti-corrosion performance for aggressive chemical environments.
Dual-Range Filtration Precision: Standard processing achieves filtration precision of 5 mm down to 200 μm across the 5–130 PPI range, while specialized manufacturing techniques extend precision down to 3–50 μm, enabling the foam to serve as both macro-scale distillation packing and micro-scale particulate filtration media within a single material platform.
High Hydrogen Absorption Capacity: Nickel exhibits significant hydrogen absorption characteristics, with absorption capacity inversely proportional to grain size. This property makes the foam particularly suitable for hydrogen-related electrochemical applications including alkaline electrolysis and metal hydride battery systems.

APPLICATION SCOPE: Validated for use as distillation column structured packing and condenser heat exchange material in chemical separation processes. Serves as a high-surface-area catalyst carrier in heterogeneous catalysis and chemical reactor engineering. Functions as an electrode current collector and active material substrate in power battery systems including Ni-MH and Ni-Cd chemistries. Applicable as industrial filtration media for liquid and gas purification, high-end decorative architectural panels, vibration-damping flooring underlayment, electromagnetic shielding enclosures, acoustic damping materials, protective packaging, and lightweight structural composites. The 99% nickel purity, plain-weave architecture, and 40 PPI open-cell morphology provide consistent mass transfer and fluid dynamics characteristics across all application domains.

PACKAGING: Supplied in custom-cut geometric dimensions per customer specification. Each unit is vacuum-sealed within low-outgassing polyethylene film and protected by rigid backing plates to preserve the open-cell pore structure and plain-weave surface integrity during transit. The dense surface oxide film formed at ambient temperature provides adequate short-term atmospheric protection; however, for applications requiring pristine metallic surfaces, inert atmosphere packaging is available upon request. Custom dimensions, thicknesses (0.5–40 mm), and PPI grades (5–130) manufactured to order.

IMPORTANT NOTICE: When handling thin nickel foam sheets (< 1 mm thickness), employ vacuum pickup tools or flat-tipped tweezers to prevent localized plastic deformation of the plain-weave structure. For high-temperature applications exceeding 500°C in oxidizing atmospheres, pre-condition the material in a reducing environment (H₂/Ar) to remove the surface oxide layer and restore maximum electrical and thermal conductivity. Note that dilute nitric acid slowly dissolves nickel; concentrated nitric acid passivates the surface and enhances corrosion resistance. The material absorbs hydrogen gas—absorption capacity increases with decreasing grain size—requiring appropriate safety considerations during hydrogen-rich electrochemical operations. Store in a desiccated environment if extended shelf life with minimal surface oxidation is required.

What performance trade-off should be considered when selecting between different PPI grades of this nickel foam for distillation column packing?

Higher PPI improves filtration precision down to 3–50 µm via special processing, but increases fluid resistance as water permeability drops below the standard ≥80% threshold. For distillation packing, lower PPI (e.g., 40 PPI) offers lower pressure drop and higher throughput, while higher PPI provides finer mass transfer surface area at the cost of reduced permeability. The 60–70% porosity and ≥98% through-hole ratio ensure consistent vapor-liquid contact across the range.

Can this nickel foam be used directly in acidic electrolyte environments without additional surface treatment?

Yes, due to its self-passivating oxide film, but compatibility depends on acid type and concentration. Dilute nitric acid slowly dissolves nickel, while concentrated nitric acid passivates and enhances corrosion resistance. For hydrogen-rich electrochemical operations like alkaline electrolysis, the material's hydrogen absorption capacity increases with decreasing grain size and requires appropriate safety measures. In oxidizing atmospheres above 500°C, preconditioning in a reducing H₂/Ar environment is needed to restore conductivity.

What handling and storage precautions are required to preserve the structural integrity and performance of this nickel foam?

For thin sheets below 1 mm thickness, vacuum pickup tools or flat-tipped tweezers must be used to avoid plastic deformation of the plain-weave structure. Store in a desiccated environment to minimize surface oxidation during extended shelf life. For high-temperature applications above 500°C in oxidizing atmospheres, pre-condition in a reducing H₂/Ar environment to remove the surface oxide layer. Additionally, the material's hydrogen absorption requires appropriate safety considerations during electrochemical operations.

Assessment

This 99% nickel 40 PPI open-cell foam provides a high-surface-area, corrosion-resistant substrate for distillation packing, catalyst support, and electrochemical electrodes, with a through-hole ratio exceeding 98% and thermal stability above 500°C, though thin sheets require careful handling to avoid plastic deformation and hydrogen absorption in fine-grained variants demands safety precautions.

Positive

High-purity nickel with self-passivating oxide: Ni >99% purity with spontaneous oxide film formation provides intrinsic acid-alkali corrosion resistance, ensuring long-term chemical stability in organic acids, alkaline solutions, and oxidizing environments without additional coatings.
Dual-range filtration and mass transfer capability: Standard processing achieves filtration precision from 5 mm down to 200 μm (5–130 PPI), while specialized techniques extend to 3–50 μm, enabling the same material to function as both macro-scale distillation packing and micro-scale particulate filter.

Trade-offs

Thin sheets prone to plastic deformation: Sheets under 1 mm thickness require vacuum pickup tools or flat-tipped tweezers during handling to avoid localized plastic deformation of the plain-weave structure, adding handling complexity for thin-gauge applications.
Hydrogen absorption requires safety consideration: Nickel exhibits significant hydrogen absorption capacity inversely proportional to grain size, necessitating appropriate safety protocols during hydrogen-rich electrochemical operations such as alkaline electrolysis or metal hydride battery use.
