Understanding Platinum Crucibles

Platinum crucibles are manufactured from platinum. Platinum has a melting point of 1 768 °C. It conducts heat evenly and resists corrosion and chemical reactions. These properties offer reliable performance in controlled experiments.

Advantages of Platinum Crucibles

The key features of platinum crucibles are as follows:

High Melting Point: Platinum maintains a melting point of 1 768 °C, which permits use in processes that require temperatures above 1 000 °C. This ensures that the crucibles preserve their form.

Chemical Inertness: Platinum does not react with most acids or bases. This resistance to corrosion minimises the chance of sample contamination.

Thermal Conductivity: Platinum exhibits effective thermal conductivity. This facilitates uniform heating and cooling during experimental procedures.

Non-toxic and Biocompatible: Platinum is non-toxic and biocompatible. It meets the criteria for usage in medical and pharmaceutical applications such as sample preparation and inorganic material synthesis.

High Purity: Crucibles are typically produced from high purity platinum to limit contamination. High purity platinum crucibles are available from Stanford Advanced Materials (SAM).

Applications of Platinum Crucibles

The properties of platinum crucibles allow them to be deployed in various sectors.

1. High-temperature Applications

Platinum crucibles are used in processes such as melting, annealing and calcination. Industries such as metallurgy, glass production and ceramics use them to manage materials at elevated temperatures.

2. Analytical Chemistry

Platinum crucibles are employed in gravimetric analysis and in melting methods. Their high thermal conductivity, chemical inertness and capability for precise mass measurement yield reproducible results.

3. Handling of Precious Metals

Platinum crucibles serve in precious metal refining, jewellery production and catalyst manufacturing. They are applied when processing gold, silver, platinum and palladium, thereby limiting contamination and material loss.

4. Semiconductor Industry

The semiconductor industry requires high purity materials and strictly controlled processes. Platinum crucibles are used in the production of semiconductors and electronic components, thereby providing a controlled environment for crystal growth, thin-film deposition and high-temperature annealing.

5. Research and Development:

Platinum crucibles are used in research and development to evaluate and test advanced materials. Their reliability and chemical inertness support the acquisition of precise measurements and analyses.

Optimal Usage Considerations

Careful handling of platinum crucibles is required to avoid damage or contamination. The crucibles should be cleaned before each use to ensure sample integrity. Storing them in a clean, dry environment preserves their condition and prevents oxidation.
