Discussion on the Main Components and Optimal Proportioning Technology of Platinum Conductor Slurry

Platinum conductor paste, as an important electronic material, has a wide range of applications in fields such as semiconductors, sensors, and LED components. Its excellent conductivity, high-temperature sintering performance, and solder resistance make it an indispensable part of the modern electronics industry. This article will be presented by Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand YB8206 Platinum Conductor PasteFor example, explore in depth the main components and the optimal ratio determination method between each component.

The main components of platinum conductor paste

Platinum conductor paste is mainly composed of three parts: platinum powder, glass binder, and carrier. These three factors work together to determine the performance of the slurry.

platinum powder

Platinum powder isPlatinum conductor pasteThe purity, particle size, and surface morphology of the core components have a direct impact on the performance of the slurry. Generally speaking,Research Platinum Brand YB8206The purity requirement for platinum powder is above 99.99%, with particle size controlled between 0.1 and 0.5 μ m to ensure high conductivity and high density of the slurry. In addition, the smoothness of the platinum powder surface is also an important factor affecting its performance.

glass adhesive

Glass adhesive is a bonding agent between platinum powder particles, which can firmly fix platinum powder on the carrier and form a continuous conductive network. When selecting glass adhesives, it is necessary to ensure that they do not undergo chemical reactions with platinum powder and have good thermal and chemical stability. At the same time, the content of adhesive also needs to be carefully controlled to ensure that the viscosity and flowability of the slurry reach the optimal state.

carrier

The carrier is the supporting material in platinum slurry, usually made of high temperature resistant and corrosion-resistant materials such as alumina. The choice of carrier also has a significant impact on the final performance of the slurry, determining its physical properties such as mechanical strength and thermal expansion coefficient.

Determination of the optimal ratio between each component

theoretical basis

surePlatinum conductor pasteThe optimal ratio of each component requires comprehensive consideration of the physical and chemical properties of the material as well as application requirements. For example, the content of platinum powder directly affects the conductivity of the slurry, while the content of glass binder affects the viscosity and flowability of the slurry. In addition, the choice of carrier also needs to be determined based on specific application scenarios.

Experimental methods

In practical operation, experimental methods are usually used to determine the optimal ratio. The specific steps are as follows:

1. Prepare samples with different ratios: Prepare multiple sets of samples with different platinum powder content, glass binder content, and carrier types according to the preset ratio scheme.
2. Performance testing: Conduct conductivity, thermal conductivity, corrosion resistance, mechanical strength and other performance tests on each group of samples, and record relevant data.
3. Data analysis: Based on test data, analyze the impact of each component on the properties of the slurry and find the optimal ratio scheme for performance.

Practical application cases

Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand YB8206For example, the company has accumulated rich experience in the research and production of platinum conductor paste. Through continuous experimentation and optimization, a platinum conductor slurry ratio scheme suitable for different application scenarios has been determined. For example, in the field of temperature measurement materials, platinum powder with a purity of 99.99% and a particle size of 0.1-0.5 μ m, combined with specific glass binders and alumina carriers, is used to prepare platinum slurries with high conductivity, stability, and reliability, which are widely used for temperature measurement in the range of -70 to 600 ℃.
