Description
Technical Parameters

NAVI Titanium supplies mixed metal oxide anodes for electrochemical systems where controlled catalytic activity and predictable electrode behavior are important. Iridium-, ruthenium-, tantalum-, and titanium-based oxide combinations can be tailored to favor oxygen evolution, chlorine evolution, or other reactions. For procurement, coating thickness uniformity and edge-area coverage are worth checking, as local coating depletion can become a failure point before the average coating condition appears abnormal.

Application

 

Mixed metal oxide anodes originated as a replacement for consumable graphite materials and gradually became an important choice for continuous electrical conversion. NAVI Titanium supplies these electrodes for applications where controlled electrochemical performance is required. Their working principle involves transferring electrical energy through catalytic oxide layers, promoting gas evolution or metal deposition while minimizing material loss. Today, these electrodes are selected for chlorine manufacturing facilities and printed circuit board plating lines, where different geometries, oxide compositions, catalytic loading levels, and dimensional specifications are chosen according to electrolyte composition, production capacity, installation layout, and maintenance schedules.

1.Chlor-Alkali Industry
 

Chlor-alkali plants typically utilize ruthenium–iridium oxide mesh, expanded mesh, or flat plate electrodes installed within membrane or diaphragm cells for chlorine generation. Common dimensions include plate thicknesses of 1.0–3.0 mm and mesh openings ranging from 5 × 10 mm to 10 × 20 mm. Catalyst loading is determined by the intended chlorine yield. Peripheral welds, electrical connection points, and suspension components are fabricated to match cell dimensions, allowing rapid exchange during scheduled shutdowns. Brine concentration, electrical loading, and chlorine output are considered when selecting electrode formats, promoting even gas evolution while lowering power demand. Multiple size options are available for pilot equipment, medium-output installations, and high-capacity chlor-alkali plants.

Manufacturing process

 

Production begins with a carefully prepared titanium substrate, where the surface is mechanically conditioned and chemically activated to promote strong bonding with the catalytic coating. The key stage is the preparation of the mixed-oxide coating solution, in which selected ruthenium, iridium, tantalum, or other oxide-forming components are proportioned according to the intended electrochemical duty. The solution is applied onto the substrate through controlled brushing, dipping, or spraying, with repeated coating cycles used to build a consistent active layer. Each pass is carefully regulated to avoid runs, bare areas, or excessive accumulation around edges and joints. The coated substrate then undergoes a controlled curing cycle that converts the deposited precursors into a stable oxide network. Multiple application and curing stages can be combined when a specific loading or surface architecture is required.

Product

 

Mixed metal oxide anodes consist of four principal sections: a metal support frame, an electrical transmission assembly, a catalytic oxide layer, and auxiliary hardware. Each section contributes to structural strength, electrical continuity, catalytic activity, or installation convenience within PCB plating equipment. NAVI Titanium provides these assemblies with specifications tailored to different plating applications. Material selection, dimensional control, noble-metal loading, conductive connections, insulation elements, and fastening accessories are coordinated according to plating bath chemistry, tank dimensions, electrical loading, and maintenance schedules, supporting continuous metal deposition together with consistent manufacturing quality across production lines.

1.Base Metal Support Assembly
 

The base metal support assembly of mixed metal oxide electrode forms the primary framework carrying every conductive element inside PCB plating equipment. NAVI Titanium supplies Grade 1 material, which is commonly selected because of its excellent formability, low weight, and outstanding chemical endurance. Expanded mesh, perforated sheet, flat plate, or tubular geometries are chosen according to tank dimensions, electrolyte circulation, and installation layout. Laser cutting, rolling, bending, welding, flattening, and heat treatment create accurate geometry while minimizing deformation. Hanging sections, reinforced edges, and supporting members maintain structural integrity during continuous production and simplify replacement during scheduled maintenance.

2. Electrical Transmission Assembly

 

Mixed Metal Oxide Anodes Components | NAVI Titanium

Electrical power enters the electrode through a conductive network linking the rectifier with every active region inside the plating tank. NAVI Titanium supplies connection assemblies configured for the required electrical loading and tank layout. This pathway is formed by copper busbars, terminal blocks, welded joints, suspension hooks, threaded fasteners, insulating brackets, and connection fittings. Every contact point receives careful finishing to minimize resistance while ensuring secure mechanical engagement. The size of busbars, connector cross-sections, fastening arrangements, and terminal positions is determined by tank dimensions, power demand, and plating output, promoting even energy delivery across the entire electrode structure.

3. Catalytic Oxide Layer Assembly
 

The MMO anode features an active oxide film formed from carefully balanced combinations of ruthenium, iridium, tantalum, and other noble-metal oxides to match copper, nickel, tin, or precious-metal plating baths. Precious-metal loading, oxide ratios, firing schedules, film depth, and bonding strength are carefully monitored throughout fabrication. Repeated high-temperature treatment produces a compact oxide layer with uniform elemental distribution, limiting unnecessary noble-metal consumption while promoting even metal deposition on complex printed circuit board patterns, including multilayer circuits, HDI panels, flexible boards, and semiconductor packaging components.

Mixed Metal Oxide Anodes Mesh | NAVI Titanium

Mixed metal oxide anodes with an expanded mesh configuration are frequently selected for membrane chlor-alkali cells because the open lattice encourages rapid gas release while promoting smooth brine circulation throughout the electrolyzer. Mesh aperture, strand width, sheet gauge, and expansion ratio are determined by electrolyzer dimensions and anticipated chlorine yield. Standard diamond openings generally range from 5 × 10 mm to 10 × 20 mm, while panel length and width are prepared to match project drawings. Connection terminals, suspension bars, reinforcing members, and outer frames are fitted before delivery. We completes each panel through repeated firing cycles together with comprehensive dimensional verification, producing an evenly distributed oxide layer and consistent fabrication results for chlorine production facilities.

3.Tubular Electrode Configuration
 

Tubular electrodes are often chosen for membrane chlor-alkali cells because their round profile promotes smoother brine movement and faster gas release within narrow electrolyzer chambers. Standard outside diameters range from 20 mm to 80 mm, with wall thicknesses between 1.5 mm and 3.0 mm. Overall length is prepared to match individual electrolyzer dimensions. Threaded fittings, terminal connections, end closures, hanging components, and sealing parts are fitted before delivery, reducing field installation time. NAVI Titanium manufactures tubular electrodes using carefully balanced ruthenium–iridium oxide formulations, controlled precious-metal content, and comprehensive dimensional verification, serving projects from demonstration facilities to large-scale chlorine plants while offering excellent installation flexibility and uniform fabrication quality.
