1、 Introduction
Co firing technology is one of the key technologies in modern electronic component manufacturing, widely used in multi-layer ceramic capacitors, chip resistors, sensors, and other fields. Platinum electrode paste has become an indispensable material in co firing processes due to its excellent conductivity, chemical stability, and high-temperature performance. However, the shrinkage rate of platinum electrode slurry during co firing process has a significant impact on the performance and reliability of the final product. This article will explore the effect of shrinkage rate of co fired platinum electrode slurry on the co firing process, and present the findings of Advanced Institute (Shenzhen) Technology Co., Ltd
Research Platinum Brand YB8203 Co fired Platinum Electrode SlurryFor example, analyze its performance in practical applications.
2、 Factors affecting the shrinkage rate of co fired platinum electrode slurry
-
The shrinkage rate of platinum electrode slurry is influenced by its formulation and particle characteristics. The particle size, distribution, and ratio of binder and solvent of platinum particles have a significant impact on the rheological properties and sintering shrinkage of the slurry. Advanced Institute (Shenzhen) Technology Co., Ltd. has achieved uniform distribution of platinum particles and ideal rheological properties by optimizing the formula of YB8203 slurry, effectively controlling the shrinkage rate during the sintering process.
-
Sintering temperature and time are key factors affecting the shrinkage rate. The sintering temperature of YB8203 platinum electrode slurry from Yanbo brand is usually around 1200 ℃, with a holding time of about 2 hours. High temperature sintering reduces the pores in the slurry, forming a denser structure, thereby improving conductivity and mechanical strength. Meanwhile, by precisely controlling the sintering temperature and time, the shrinkage rate during the sintering process can be effectively reduced.

Advanced Institute of Sintering Technology (Shenzhen) Co., Ltd. adopts a step-by-step sintering process, first performing medium and low temperature debinding sintering, and then conducting high temperature strengthening sintering. This process utilizes the reaction sintering oxidation expansion effect to offset some shrinkage deformation, thereby effectively controlling the shrinkage rate. In addition, adding sintering expansion agent is also an effective method to control the shrinkage rate.
-
The sintering environment, such as atmosphere and pressure, also has a significant impact on the shrinkage rate.

3、 The influence of shrinkage rate on the performance of co fired products
-
The shrinkage rate of platinum electrode slurry directly affects the conductivity of the electrode. The resistivity of YB8203 paste from Yanbo brand after sintering is 1.65 μ Ω· cm, which is about 21% lower than the unsintered state, demonstrating excellent conductivity. By controlling the shrinkage rate, the density and conductivity of the electrode can be ensured, thereby improving the electrical performance of the product.
-
The mechanical strength after sintering is an important indicator for measuring the sintering quality of platinum slurry. The experimental results show that the tensile strength of the sintered YB8203 slurry of the research platinum brand is 280 MPa, which is about 17% higher than the unsintered state. Reasonable shrinkage control can ensure the mechanical stability of electrodes in high-temperature environments, reduce cracking and delamination phenomena.
-
The control of microstructure shrinkage rate also affects the microstructure of platinum electrodes. Smaller and uniformly distributed platinum particles can provide more active sites, increase the contact area between reactants and catalysts, and thus enhance catalytic activity. By optimizing the sintering process, it can be ensured that the platinum electrode forms a stable and suitable crystal structure and surface morphology.
-
During the co firing process, the compatibility with the substrate,
Platinum electrode slurryThe shrinkage rate needs to match the shrinkage rate of the substrate. If the two do not match, it may cause problems such as interface layer splitting, warping, and cracking. The YB8203 slurry of Yanbo brand has achieved a good match with the substrate by optimizing the formula and sintering process.
4、 Practical application cases
The YB8203 co fired platinum electrode slurry from Advanced Institute (Shenzhen) Technology Co., Ltd. has shown excellent performance in practical applications. For example, in co fired biosensor electrodes, the slurry can accurately fill the small gaps between sensor elements, form stable conductive pathways, and significantly improve the sensitivity and response speed of the sensor. In addition, its excellent conductivity and mechanical strength make it an ideal electrode material in high-temperature electrochemical devices.
5、 Conclusion
Co fired platinum electrode slurryThe shrinkage rate plays a crucial role in the co firing process. By optimizing the slurry formula, sintering process, and sintering environment, the shrinkage rate can be effectively controlled, thereby improving the electrical, mechanical, and reliability properties of the product. The YB8203 co fired platinum electrode paste of Advanced Institute (Shenzhen) Technology Co., Ltd. has shown broad application prospects in the field of electronic component manufacturing due to its excellent performance and stable shrinkage control.
