Description and Specifications of Platinum Conductive Paste

Platinum Conductive paste is a mixture of divided platinum particles and a binder. It is also known as Platinum Conductive Ink. It is applied to a substrate using a screen-printing process. After applying the paste, it is fired at a high temperature to sinter the particles together. This results in a thin, uniform layer of platinum that is highly electrolytically active.

It is a valuable material for various applications because it is conductive, has a high melting point, and is a suitable catalyst. Due to these characteristics, it can be used in electrochromic, fuel, and solar cells.

Here are some more details about platinum paste:

• The typical particle size of platinum in the paste is 1-100 nm.
• The binder used is a polymer, such as polyvinyl alcohol.
• The firing temperature of the paint is typically 420 – 450 °C.

Although this paint is expensive, its high performance makes it a cost-effective choice for many applications. In dye solar cells, the counter-electrode is the part of the cell that receives electrons from the electrolyte. The platinum on the counter-electrode helps to move electrons from the electrolyte to the cell, which makes the cell work better.

This versatile solution can enhance a wide range of materials, including metal, wood, ceramics, and glass. It is easy to use and can be applied with various tools, making it an excellent option for seasoned artists and beginners. Platinum Conductive Paint has the same raw ingredients as Silver Conductive Paint, except for the metal solids. The processing is expected to be the same, but the sintering of metal particles occurs at much higher temperatures. The sublimation of the metal in a vacuum is also expected to occur at higher temperatures.
