Performance of Corrosion Resistance of Silver Platinum Electrode Paste for Sensors in Different Media

With the rapid development of sensor technology, the performance of electrode paste has become one of the important factors affecting the lifespan and accuracy of sensors. Developed by Advanced Institute (Shenzhen) Technology Co., Ltd Research Platinum Brand YB8301 Silver Platinum Electrode PasteIt has attracted much attention for its unique formula and excellent comprehensive performance. Among them, corrosion resistance is a key indicator to measure whether the electrode slurry can operate stably in complex working environments. This article will focus on exploring its performance in different media.

The experiment used the YB8301 silver platinum electrode slurry from Advanced Institute (Shenzhen) Technology Co., Ltd. to prepare standard electrode samples. Common media have been selected, including acidic solutions (such as dilute sulfuric acid, hydrochloric acid), alkaline solutions (sodium hydroxide solution), salt solutions (sodium chloride solution), and organic media (ethanol, acetone). Soak the electrode samples in different media and conduct accelerated corrosion experiments under specific temperature and time conditions. By measuring the resistance changes of the electrode before and after corrosion, observing the surface morphology (using scanning electron microscopy, SEM), and analyzing its composition (energy dispersive spectroscopy, EDS), the corrosion resistance performance is comprehensively evaluated.

In dilute sulfuric acid and hydrochloric acid solutions, YB8301 silver platinum electrode pasteExhibiting good corrosion resistance. Due to the inherent acid resistance of silver and platinum, and the formation of a dense protective film by additives in the slurry, the corrosion of the electrode by the acid solution is slowed down. The experimental results showed that after soaking in an acidic solution of a certain concentration and temperature for a period of time, the resistance change of the electrode was small. SEM images showed only slight corrosion marks on the electrode surface, mainly some local small pits. EDS analysis did not detect obvious element loss, indicating that the electrode slurry can maintain good stability and conductivity in acidic media, providing a reliable electrode material selection for sensors working in acidic environments.

In alkaline sodium hydroxide solution, the electrode slurry also exhibits satisfactory corrosion resistance. Silver is relatively stable in alkaline environments, while platinum's antioxidant properties further enhance the electrode's alkali resistance. After prolonged soaking, the appearance of the electrode showed no significant changes, and the resistance value remained within a reasonable range. Microscopic analysis reveals that a thin passivation film has formed on the surface of the electrode, preventing further penetration and corrosion of alkaline substances, ensuring the long-term reliability of the electrode in alkaline media, and suitable for sensor applications related to alkaline environments, such as certain biosensors and industrial alkaline solution monitoring sensors.

In a solution of sodium chloride salt, YB8301 electrode pasteThe anti-corrosion performance is quite outstanding. Although salt solutions have certain conductivity and may accelerate electrochemical corrosion, the components in the slurry effectively suppress this trend. After being immersed in a salt solution, the electrode showed only a small amount of chloride ion adsorption on its surface, without obvious accumulation of corrosion products or damage to the electrode structure. The resistance change was not significant, ensuring accurate measurement of the sensor in saltwater environments. In organic media such as ethanol and acetone, due to the relatively low chemical activity of these media, the electrode slurry exhibits extremely high stability and almost no corrosion reaction occurs. The various performance parameters of the electrode are basically the same as before immersion, providing a guarantee for sensor applications in organic environments or that may come into contact with organic solvents.

The YB8301 silver platinum electrode paste from Advanced Institute (Shenzhen) Technology Co., Ltd. exhibits excellent corrosion resistance in various media such as acidic, alkaline, salt solutions, and organic media. Its stable chemical composition and unique microstructure enable it to maintain the integrity and conductivity of electrodes in complex chemical environments, providing a solid foundation for the long-term stable operation of sensors under various harsh working conditions. This research achievement further expands the application prospects of the electrode slurry in a wide range of fields, and is expected to promote the application and development of sensor technology in more harsh environments, providing strong support for the technological upgrading of related industries.
