With the rapid development of biotechnology, the application of biosensors in medical, environmental monitoring, food safety and other fields is becoming increasingly widespread. Co fired platinum electrode slurry, as a high-performance material, exhibits unique advantages in the manufacturing of co fired biosensor electrodes. This article will focus on the introduction of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand YB8203 Co fired Platinum Electrode SlurryApplication in electrodes of co fired biosensors.

Characteristics of Co fired Platinum Electrode Slurry

Co fired platinum electrode slurry is a composite material composed of platinum powder, glass binder, and carrier, which has high conductivity, stability, and corrosion resistance. As a star product of Advanced Institute (Shenzhen) Technology Co., Ltd., the YB8203 co fired platinum electrode slurry of Yanbo brand has the following significant characteristics:

1. High conductivity: Platinum powder has excellent conductivity due to its atomic structure and electron cloud distribution, which makes it easy for electrons to move freely in the platinum lattice, ensuring smooth transmission of current in the sensor.
2. Stability: Platinum can maintain stable performance in harsh environments such as high temperature and high pressure, thanks to its chemical bond stability at high temperatures and the characteristic of not easily deforming under high pressure, providing strong guarantees for the long-term stable operation of sensors.
3. Corrosion resistance: Platinum can resist the erosion of various corrosive substances because a dense oxide film is formed on the surface of platinum to prevent further penetration of corrosive media, thereby extending the service life of the sensor.

Manufacturing of electrodes for co fired biosensors

The manufacturing process of co fired biosensor electrodes involves multiple key steps, among which the application of the YB8203 co fired platinum electrode slurry from Yanbo brand is crucial. The following are the main steps of the manufacturing process:

1. Slurry preparation: willResearch Platinum Brand YB8203 Co fired Platinum Electrode SlurryMix evenly with organic solvents, binders, and other auxiliary materials to form a uniform slurry. In this process, the ratio of YB8203 slurry and auxiliary materials needs to be precisely controlled to ensure the rheological properties and stability of the slurry.
2. Coating and drying: The prepared slurry is coated onto a ceramic substrate or other base material, and then dried to ensure uniform adhesion of the slurry to the base material. The high fluidity of YB8203 slurry from Yanbo brand enables it to better cover the surface of the substrate, while its rapid drying characteristics help improve production efficiency.
3. Co firing treatment: Place the substrate coated with slurry in a high-temperature furnace for co firing treatment. At high temperatures, platinum powder reacts chemically with glass binder to form a dense conductive network. The YB8203 slurry of Yanbo brand exhibits excellent sintering performance during this process, ensuring the uniformity and stability of the conductive network.
4. Electrode forming and post-processing: After co firing, the electrode is formed and processed, such as cutting, polishing, etc., to obtain the required electrode shape and size. The high strength and toughness of YB8203 paste from Yanbo brand make it less prone to cracking or deformation during post-processing, ensuring the final quality of the electrode.
