1、 Material and structural characteristics

1. Base material

Using titanium as the substrate, it has high mechanical strength, low density, and ease of processing, with a cost only one-third to one-fifth of traditional precious metal electrodes.

The surface is coated with ruthenium and iridium oxides through thermal decomposition or electroplating, forming a nano porous composite catalytic layer with a doping

 ratio of 10% -30%, optimizing reaction activity and stability.

2. Coating process

The coating thickness is 0.5-5 μ m, and after high-temperature sintering at 500-600 ℃, it is tightly bonded to the titanium substrate, with adhesion reaching ASTM D3359 

standard level B.

2、 Corrosion resistance performance

1. Environmental adaptability

It can operate stably for a long time in strong acids, strong bases, and highly oxidizing media, and can withstand extreme environments with pH values ranging from 0-14.

Excellent resistance to seawater corrosion, with a service life of over 6 years, far exceeding traditional graphite electrodes and lead based alloy electrodes.

2. Anti passivation ability

By adding elements such as tantalum and tin to improve the coating, the dissolution and passivation of oxides are slowed down, and the upper limit of the working voltage

 is increased to 1.8V.

3、 Electrochemical performance

1. Conductivity and energy consumption

The resistivity is lower than that of pure titanium electrodes, the DC power consumption is reduced by 10% -20% compared to traditional electrodes, and the electrolysis efficiency

is improved by 15% -30%.

The current density can reach 3000A/m ², with excellent conductivity uniformity and electrode loss rate below 0.1g/kA · h.

2. Catalytic activity

The overpotentials for chlorine and oxygen evolution were as low as 0.1V and 0.25V, respectively, significantly increasing the reaction rate.

In the electrolysis of water for hydrogen production, the current efficiency of oxygen evolution reaction is increased by 40% -60%, and the purity of hydrogen production 

reaches 99.99%.

4、 Service life and stability

1. Life Advantage

Stable operation for over 4000 hours under normal operating conditions, with a lifespan 3-5 times that of lead anodes.

By pre oxidation treatment and gradient coating design, the propagation of microcracks can be delayed, and the lifespan can be extended to 6 years.

2. Dimensional stability

During the electrolysis process, there is no deformation or dissolution, and the electrode spacing is constant to avoid the risk of short circuit and ensure continuous production.

5、 Cost effectiveness

1. Economic viability

The material cost is only one-third to one-half of that of pure platinum anodes, but the electrochemical performance is similar.

Waste electrodes contain precious metals, with a recycling value of 300-3000 yuan/kg, reducing overall usage costs.
