Application

The Cadmium single crystal disc, with dimensions of 10mm in diameter and a thickness ranging from 1-3mm, oriented at (100) with a tolerance of ±0.5°, serves a crucial role in materials science and industrial applications. Cadmium is a lustrous, silver-white metal with a bluish tint, known for its ductility and malleability, which allows it to be shaped with ease. Despite its stability under normal conditions, cadmium can tarnish in the air and is flammable as a powder. Its unique properties, including corrosion resistance and applicability in low-melting-point alloys, make it valuable in various settings. Cadmium discs are integral in research and development, particularly in fields requiring precise crystallographic orientation, and they support advancements in electronics, coatings, and specialized alloys. Due to cadmium's highly toxic nature, handling requires careful adherence to safety protocols to prevent exposure.
