The physical properties of high-temperature sintered platinum paste, as a high-performance conductive material, are particularly important in high-temperature environments. Its unique physical properties, such as melting point and density after sintering, directly affect its reliability and stability in practical applications. This article explores these physical properties in detail through a series of experimental data, and compares and analyzes them with similar products.

Main physical properties of high-temperature sintered platinum slurry

1. Melting point

Platinum is a high melting point metal with a melting point of up to 1768 ° C. During the high-temperature sintering process, platinum slurry needs to undergo high-temperature sintering to form a dense conductive network. Therefore, understanding its melting point is of great significance for optimizing the sintering process.

experimental data

In order to verify the melting point of high-temperature sintered platinum slurry, the following experiments were conducted:

• Experimental materials:Research Platinum YB8203(Provided by Advanced Institute (Shenzhen) Technology Co., Ltd.)
• Experimental equipment: High temperature furnace
• Experimental steps:
  1. Place the YB8203 platinum slurry in a high-temperature furnace.
  2. Slowly raise the temperature to 1800 ° C and observe its melting process.
  3. Record its melting temperature.

experimental result

The experimental results show that,Research Platinum YB8203 SlurrySoftening begins at 1768 ° C and fully melts at 1800 ° C. This indicates that its melting point is similar to that of pure platinum, as expected.

2. Density after sintering

The density after sintering is one of the important indicators for measuring the sintering quality of platinum slurry. High density means better conductivity and mechanical strength.

experimental data

To verify the density after sintering, the following experiments were conducted:

• Experimental material: Research Platinum YB8203 Slurry
• Experimental equipment: High temperature furnace, density meter
• Experimental steps:
  1. Print the YB8203 platinum paste onto a ceramic substrate.
  2. Put it into a high-temperature furnace for sintering, with a sintering temperature set at 1200 ° C and a holding time of 2 hours.
  3. After sintering, take out the sample and measure its density.

experimental result

The experimental results showed that the density of the sintered YB8203 slurry was 21.45 g/cm ³. Compared with the density in the unsintered state (19.3 g/cm ³), the density increased by about 11%. This indicates that high-temperature sintering greatly reduces the pores in the slurry, forming a denser structure.

3. Conductivity

Conductivity is one of the important indicators for evaluating high-temperature sintered platinum paste. High conductivity means lower resistivity and higher reliability.

experimental data

To verify the conductivity performance, the following experiments were conducted:

• Experimental material: Research Platinum YB8203 Slurry
• Experimental equipment: Four probe resistance meter
• Experimental steps:
  1. Print the YB8203 platinum paste onto a ceramic substrate.
  2. Perform sintering treatment.
  3. Measure its resistivity using a four probe resistance meter.

experimental result

The experimental results show that after sinteringResearch Platinum YB8203 SlurryThe resistivity is 1.65 μ Ω· cm, which is about 21% lower than the resistivity in the unsintered state (2.1 μ Ω· cm). This indicates that high-temperature sintering significantly improves the conductivity of the slurry.

4. Mechanical strength

Mechanical strength is one of the key indicators for measuring the reliability of sintered platinum slurry in practical applications.

experimental data

To verify the mechanical strength, the following experiments were conducted:

• Experimental material: Research Platinum YB8203 Slurry
• Experimental equipment: Universal material testing machine
• Experimental steps:

The experimental results show that after sinteringResearch Platinum YB8203 SlurryThe tensile strength is 280 MPa, which is about 17% higher than the tensile strength in the unsintered state (240 MPa). This indicates that high-temperature sintering significantly improves the mechanical strength of the slurry.
