Features

Ruthenium-Iridium-Titanium (Ru-Ir-Ti) Mixed Metal Oxide (MMO) Anodes with RuO₂ + IrO₂ coating on Grade 1 or Grade 2 Titanium substrate, manufactured for high-performance electrochemical processes including oxygen and chlorine evolution.
Exceptional corrosion resistance provided by titanium oxide layer, enabling stable operation in aggressive acidic, alkaline, and chloride-rich environments even at high current densities.
Superior electrocatalytic activity and synergy between RuO₂ and IrO₂ for enhanced oxygen evolution reaction (OER), chlorine evolution, and organic compound oxidation with broad selectivity.
Comprehensive range of anode configurations: Plate, Mesh, Rod, Tube, Wire, and custom shapes to optimize surface area and current distribution.
High current density capability up to 5,000 A/m², noble metal loading 8–13 g/m², coating thickness 6–15 µm, and operating voltage typically ≤24 V.
Wide operating range: pH 1–14, temperature up to 80°C, with mechanical robustness and long-term dimensional stability for reliable performance.
Extended service life (1–3 years in harsh conditions; up to 8 years in milder environments) with reusable titanium substrate after coating refresh.
Cost-effective, low-maintenance design with high efficiency, low overpotential, and full compatibility with titanium equipment for complete electrochemical systems.

Packing & Shipment

To ensure product safety during storage, handling, and international transportation, platinized titanium (Pt-Ti) anodes are packed with corrosion protection and impact protection measures according to anode type, size, quantity, and shipping mode.

Item	Packing / Shipment Method
Internal Protection	Anodes are thoroughly cleaned, dried, and all platinum-coated surfaces are protected with non-abrasive materials before packing.
Sealing Protection	Each anode or set is individually placed in sealed PE bags or vacuum-sealed packaging to prevent dust, moisture, and contamination.
Surface Protection	Critical coated surfaces are covered with soft non-woven fabric, EPE foam liners, or protective sheets to prevent scratches.
Individual Packing	Small or standard anodes are individually wrapped with PE film and packed in sturdy plywood boxes or export-grade wooden crates with sufficient cushioning materials.
Large / Custom Anode Packing	Larger or complex anodes (e.g., long tubular or large mesh) may be partially disassembled or secured separately; each component is clearly labeled with assembly instructions and fixed on wooden pallets or reinforced export crates.
Shock Protection	High-density foam padding, internal bracing, and heavy-duty strapping are used to prevent movement and impact during transit.
Moisture Control	Desiccant bags and humidity indicator cards are placed inside the sealed package to control moisture.
Marking	Package labels include product name, type (mesh/sheet/rod/wire/tubular), dimensions, coating thickness, quantity, net/gross weight, and shipping marks.
Shipping Mode	By sea (FCL / LCL), air freight, or multimodal transport depending on order quantity and delivery requirements.
Documents	Packing list, commercial invoice, certificate of origin, coating thickness test reports, material certificates, and inspection documents provided.

Handling Notes:

Anodes should be stored in a dry and clean environment before installation.
Lifting and handling must follow the marked lifting points and package instructions.
Anodes may be packed individually, in sets, or as complete assemblies as required.
Special export packing (e.g. steel crates or temperature-controlled) is available upon request.
