Titanium Felt: The Ultimate FAQ Guide
If you want to learn more details about Filson or Filson titanium felt, all information you are looking for is right here.
Keeping reading and you will get what you want to know about Filson titanium felt.
Consider the following factors to determine the price of titanium felt:
- The purity of titanium
Filson provides standard titanium material with different purity(TA1/TA2/TA3/TA4) to fabricate titanium felt. The higher the titanium purity, the higher the price is. You can choose proper purity according to your applications.
- Thickness of titanium felt
The common thickness of titanium felt is ranging from 0.25 to 1mm. Different thickness are produced with different quantity of fibers.
- The porosity of titanium felt
As a new energy material, porosity is essential to the characteristics of titanium felt, especially electrical conductivity.
With the porosity design of 53% to 90%, Filson titanium felt can increase or decrease its surface area to meet your electrical conductivity needs.
Certainly, the higher the porosity, the more you will pay.
- Whether to be platinized
In order to avoid the oxidation and operate better under high pressure environment, Filson offers you platinized titanium felt.
Whether to be platinized depends on your design. If you need platinized titanium felt, the price will be higher than common titanium felt.
Filson can provide one-step and OEM solution for titanium felt. When you choose Filson titanium felt, please send us your desired specifications or just select from following:
- Common thickness of titanium felt can be fabricated into 0.2mm, 0.25mm, 0.4mm, 0.6mm, 0.8mm.
- The porosity of titanium felt ranges from 53% to 90%.
- Titanium felt can perform normally with 1bar to 6 bar pressure environment.
- Common shape are square, disc, candle, wave or others to fit your equipment.
- Titanium felt has high filtration efficiency up to 99%.
- The electrical conductivity of titanium felt can be designed to 2.38 x 106 S/m.
Being able to be cleaned through chemical cleaning, ultrasonic cleaning or other cleaning methods, titanium felt is reusable. And Filson titanium felt has longer lifespan to be used for 2 years.
We fabricate titanium felt through the following procedures below:
- Place the titanium felt in a vacuum sintering furnace and heat up to between 400℃ and 500℃. Maintain these temperature for 1 to 3 hours.
- Conduct low-temperature sintering. Then obtain a low temperature titanium felt after natural cooling.
- Compress the low-temperature titanium felt through the hydralic press to achieve high porosity ranging from 60% to 90%.
- Return the compressed titanium felt into a vacuum furnace and heat between 800℃ and 950℃. Maintain the temperature for 30 to 45 minutes.
- Conduct high-temperature sintering. Allow it to cool naturally to achieve quality titanium felt.
The main function of platinum coating is mainly to shorten oxidation and maintain the electrical conductivity of titanium felt.
When you use titanium felt in a high pressure environment than ambient pressure usually between 1 bar and 3 bars, there will be oxide coating comes into being on the surface of titanium felt. As a result, the interfacial resistance in the cell will be increased, and the electrical conductivity conductivity will be decreased.
At this time, platinized titanium fiber felt had better be chosen to prevent oxidation and stabilize the electrochemical performance of titanium felt.
Being regarded as a new energy material, titanium is popular in electrode and power industry in recent years. Filson titanium felt is fabricated with pure titanium, and its electrical conductivity at 20℃ can reach 2.38 x 106 S/m.
Titanium felt is ideally applied in electrolyzer stacks as the flow field or diffuser material, especially on the oxygen anode side. Besides, it can also be used in PEM water electrolysis hydrogen industry, PEMFC fuel cells industry, etc.
If you choose platinized titanium fiber felt, the platinum coating can also conduct electricity and maintain stable under the oxygen and high pressure environment. Therefore, the electrical conductivity of titanium felt will be stabilized.
