Application
The purpose of the cadmium single crystal, measuring 15mm in diameter and 50mm in length with a (100) orientation and ±2° precision, is to serve as a highly specialized material for industrial and scientific applications where the unique characteristics of cadmium are beneficial. Cadmium's malleable and ductile properties, along with its lustrous silver-white appearance with a bluish tinge, make it suitable for environments requiring corrosion resistance and high stability. This crystal is particularly useful in research settings, where precise material orientation is crucial, and in technological applications such as coatings, specialty alloys, and electronic compounds. Despite its advantages, the use of cadmium requires careful handling due to its toxic nature, and its disposal must be managed to minimize environmental impact.
