Overview of Insoluble Electrode for electrolyze seawater with Iridium oxide/Platinum dispersed titanium
Titanium (Ti) is a chemical element with the atomic number 22 and is symbolized as Ti on the periodic table. It belongs to the transition metals group and is known for its low density, high strength-to-weight ratio, and exceptional corrosion resistance. Discovered in 1791 by William Gregor, titanium has become a vital material across numerous industries due to its unique combination of properties.
Feature of Insoluble Electrode for electrolyze seawater with Iridium oxide/Platinum dispersed titanium
-
Low Density and High Strength: Titanium is about 45% lighter than steel but possesses similar strength, making it ideal for applications where weight reduction is critical without compromising strength.
-
Corrosion Resistance: It forms a passive oxide layer that protects the underlying metal from corrosive substances, including sea water and chlorine, making it highly resistant to corrosion.
-
Biocompatibility: Titanium is well-tolerated by the human body and doesn’t cause adverse reactions, which is why it’s widely used in medical implants and surgical instruments.
-
Heat Resistance: With a melting point of 1,668°C (3,034°F), titanium can withstand high temperatures, making it suitable for aerospace and automotive applications.
-
Non-Magnetic and Non-Toxic: These properties make titanium ideal for applications in MRI machines and other sensitive electronic devices.
-
Fatigue Resistance: Titanium demonstrates excellent resistance to metal fatigue, crucial in cyclic loading applications such as aircraft parts.

Parameters of Insoluble Electrode for electrolyze seawater with Iridium oxide/Platinum dispersed titanium
The selection of the ideal insoluble electrode for electrolyze seawater depends on various factors such as electrode material, application temperature, pH, and dissolved metal ions. Here is an example of an electrolyte composition:
Electrolyte composition: NaCl, KCl, Al2(SO4)3, CuSO4, FeSO4, SiO2
The desired cell potential (pH) can be calculated using the electrochemical equation below:
pH = 7.5 + Vd
where:
Vd = Standard D audiometry reading at room temperature
pH = Ideal electric potential
To determine the best electrode, we need to select the appropriate quantity of each metal ion required by the electrolysis reaction. For NaCl in, the recommended concentration is 0.01 mEq/L.
Here’s a step-by-step guide to selecting the right electrode:
1. Choose the correct electrode size: The electrode should be wide enough to allow for maximum flow rate without limiting the potential drop. A typical cathode diameter is about 3 mm, while a plunger diameter is typically around 1-2 mm.
2. Consider the working voltage: The working voltage should be high enough to ensure efficient discharges and minimal potential drop, but not too high to affect the stability of the system.
3. Calculate the cell potential: Use the ideal electrical potential formula to calculate the cell potential for the chosen electrode material. For NaCl, the cell potential is approximately 7.5 mV at standard D audiometry reading at room temperature.
4. Measure the conductivity of the selected electrode: Measure the conductivity of the selected electrode material and compare it to other materials that have similar potential drops and electrolytes. Use this information to select the best electrode for your application.
In summary, the ideal electrodes for electrolyze seawater would be high-quality Ni/Pd/Si catalysts or Au/Ra/Sn interfaces, which meet the requirements mentioned above.
