Platinum is an extremely rare metal, used not only in electronics and medical device manufacturing, but also in jewellery and for certain chemical reactions. Platinum compounds have been used as catalysts for fuel cells, producing clean energy with no air pollution. Platinum compounds can also be used as catalysts in industrial chemical reactions, such as oil refining, synthetic rubber manufacturing, and pharmaceutical production.
Platinum is usually obtained as a by-product of gold, copper and nickel mining, and is extracted by smelting and complex chemical processes. However, much of the platinum used in industry is obtained through a process known as fire-refining. With this process, platinum fillings, or solders, made of platinum scrap and other precious metal compounds, are melted in a special kiln and purified. The resulting material is a smooth, gray, brittle powder known as Platinum Paste, or PGA.
Platinum Paste is the ideal material for making electronic and medical devices, due to its high level of conductivity, excellent corrosion resistance, and extremely low weight. In many cases, it can be used as a direct replacement for gold or silver pastes to reduce costs in the manufacturing process. Furthermore, its low vapor pressure, especially when heated, allows for precise control of the deposition process.
Because of its unique properties, Platinum Paste is often used to bind and secure components in electronic devices, such as switching circuits, transistors, and diodes. It is also used to form interconnects within printed circuit boards, and helps to protect the board from corrosion. Its high melting point and low thermal spiking makes it an excellent conductor of electricity, while its high resistivity allows for safe and efficient power supply control in automotive and military applications.
Additionally, because it is non-toxic and hypoallergenic, Platinum Paste is often used in medical device applications, such as catheters and pacemakers. Due to its low biocompatibility, it offers superior protection against infections and other biocompatibility issues. Furthermore, it is often used in medical implants, as its low reactivity ensures that the material will not interact with the bodys delicate environment.
In summary, Platinum Paste is an essential and versatile material used in the production of electronic and medical devices. Its unique properties offer a variety of advantages, such as high conductivity, excellent corrosion resistance, low weight, and low thermal spiking. Additionally, it is a non-toxic and hypoallergenic material that is well-suited for medical device applications. For these reasons, Platinum Paste is a highly popular and valuable material in the manufacturing industry.
