The chemical symbol for platinum is Pt. Platinum is a more precious metal than gold due to its excellent natural properties and rare reserves in nature, making it difficult to mine.

Platinum has the following four characteristics:
1. Excellent physical properties, with a silver white luster and a high melting point, reaching 1773 ℃.
2. The density is very high, at 21.4 grams per centimeter.
3. It has stable chemical properties and is not prone to chemical reactions with other substances.
4. The resistivity is relatively high.

Due to its high resistance, high melting point, and good ductility, platinum is often used as an electrode, electrical contact point, etc. in special electric melting. In the silicone industry, some catalysts also add platinum, commonly known as platinum catalysts, which are widely used in electronic potting adhesives in the electronics industry.
