Precious metal - Names and Identifiers
Precious metal - Introduction
Precious metal refers to a metal that has a low content in the earth's crust, a high price, extremely high chemical stability and good electrical conductivity. Common Precious metals include gold (Au), silver (Ag), platinum (Pt), palladium (Pd), rhodium (Rh), and ruthenium (Ru), among others.
the nature of Precious metal:
1. Chemical stability: Precious metal has high corrosion resistance and is not easy to be oxidized or corroded.
2. High density: Precious metal has a higher density and is generally heavier than common metals such as iron and copper.
3. Good conductivity: Precious metal is an excellent conductor and is widely used in electronic devices, electronic components and other fields.
4. high gloss: Precious metal has a unique gloss, so it is often used in jewelry production.
Use of Precious metal:
1. Jewelry production: gold, silver and other Precious metal are often used to make jewelry, giving it high value and beauty.
2. Wealth preservation: Precious metal is seen as a form of investment and preservation of value, especially gold and silver.
3. Electronics industry: Precious metal's good conductivity makes it widely used in electronic devices, circuit boards, electrodes, etc.
4. catalyst: platinum, palladium and other Precious metal are commonly used as catalysts to promote chemical reactions.
5. medical industry: Precious metal is used in the production of medical devices, artificial joints and other medical devices.
the preparation method of Precious metal:
Precious metal is generally obtained through the extraction, smelting and processing of Precious metal in ore. Among them, gold and silver can be extracted from ore by chemical leaching, gravity beneficiation, flotation and other methods. Platinum and palladium, on the other hand, require complex smelting and refining processes.
Safety information about Precious metal:
1. Precious metal is generally relatively stable and non-toxic in the solid state, it needs to be safe when dissolved or melted.
2. Due to the high price of Precious metal, care should be taken when using and handling to avoid waste and loss.
3. Precious metal such as platinum and palladium are commonly used as catalysts. Care should be taken to avoid contact with skin and inhalation of dust and gases to prevent allergies and respiratory problems.
4. When extracting, smelting and processing Precious metal, it is necessary to strictly abide by relevant safety operation procedures and use appropriate protective equipment.
