Application
The cadmium single crystal, with a diameter of 15mm (0.59in) and a length of 50mm (2.0in) in random orientation, serves a range of industrial and research purposes. Cadmium's unique properties-it is a ductile, malleable, silver-white metal with a bluish tint and a melting point of 321°C-make it valuable in specialized applications, despite its toxicity at low concentrations. This single crystal form of cadmium is often utilized in fields involving metal plating and electroplating, where its corrosion-resistant nature is beneficial. Additionally, its use extends to applications in electronic compounds, specialty alloys, and as a component in pigments and stabilizers. The stability and calculable behavior of cadmium single crystals make them suitable for use as catalysts in chemical reactions. It's crucial to handle this element with care due to its potential health risks, ensuring all safety measures are followed during its utilization in industrial processes.
