AI Technical Summary

Benefits of technology

This new type of material called Iridium tungsten can be used for various applications such as coatings on electronic devices or solar cells that have improved performance compared with traditional materials like tantalum oxide (TaO2). It's highly effective at producing less heat than other alternatives while still being resistant to cracks over time.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the durability of coatings applied over certain types of elecrochromes (electrocatalysts) made from materials like ruthenium or tantalum for use at elevated temperatures during these industries due to their unique properties.

Embodiment 1

[0019] A kind of iridium tantalum coating liquid, comprises the component of following parts by weight:

[0020]

Embodiment 2

[0022] A kind of iridium tantalum coating liquid, comprises the component of following parts by weight:

[0023]

Embodiment 3

[0025] A kind of iridium tantalum coating liquid, comprises the component of following parts by weight:

[0026]

[0027]

[0028] The iridium and tantalum coating solutions in the above three examples were all coated on the titanium plate 15 times, and after each coating, they were sintered at a temperature of 520°C, and finally cooled to room temperature. After testing, the three examples formed The iridium-tantalum coatings all have high activity, high efficiency and energy-saving effects, and through scanning electron microscopy, the three iridium-tantalum coatings are all uniform, have low porosity, and are not easy to crack, so they have a long life, especially the iridium-tantalum coatings in Example 1. Liquid coating works best.

Abstract

The invention discloses a high-efficiency high-activity iridium-tantalum coating solution which is prepared from, by weight , 20-30 parts of chloroiridic acid, 30-40 parts of tantalum chloride, 3-5 parts of titanium tetrachloride/ titanium trichloride, 0.5-2 parts of stannic chloride, 40-60 parts of hydrochloric acid and 5-10 parts of aqueous alcohol solutions. An iridium-tantalum coating preparedfrom the high-efficiency high-activity iridium-tantalum coating solution is high in activity and high in efficiency, saves energy, and is low in uniform porosity, not likely to crack and long in service life.
