Cadmium
Overview
Cadmium (chemical symbol Cd) is a soft, bluish-white metal that belongs to Group 12 of the periodic table, alongside zinc and mercury. It is a relatively rare element found in the Earth's crust and is commonly obtained as a byproduct during the extraction of zinc ores. Cadmium has been used in various applications due to its unique properties, but its use is closely regulated due to its toxic nature.
Properties
Cadmium has several distinctive properties that influence its applications. It has an atomic number of 48 and an atomic mass of 112.41 u. Cadmium is a relatively dense metal with a density of 8.65 g/cm³ and a melting point of 321.1 °C. It has a boiling point of 767 °C and is known for its corrosion resistance, which makes it valuable in various industrial processes. Cadmium is also a poor conductor of heat and electricity compared to other metals. Due to its softness, it can be easily cut or shaped, but it is also toxic and requires careful handling.
Applications and Uses
Cadmium is used in several key industrial and technological applications. In the battery industry, cadmium is a crucial component of nickel-cadmium (Ni-Cd) batteries, which are used in portable electronics, power tools, and emergency lighting due to their reliable performance and ability to recharge. Cadmium is also used in electroplating to provide a protective coating on steel and other metals, enhancing their resistance to corrosion and wear.
In the electronics industry, cadmium compounds are used in the manufacture of thin-film solar cells and as pigments in various types of paints, ceramics, and plastics, providing vibrant colours and stability. Cadmium telluride, a compound of cadmium, is used in the production of high-efficiency solar panels. Despite its usefulness, cadmium's toxicity poses environmental and health risks, leading to increased regulation and efforts to find safer alternatives.
Safety and Environmental Impact
Cadmium is highly toxic and can cause serious health issues if ingested or inhaled. Long-term exposure can lead to kidney damage, lung disease, and bone damage. Due to these health risks, stringent regulations are in place to manage cadmium use and disposal, and efforts are ongoing to reduce its environmental impact and find less harmful alternatives.
Summary
Cadmium is a soft, bluish-white metal with applications in batteries, electroplating, and electronics, including thin-film solar cells and pigments. Its properties, such as corrosion resistance and ease of shaping, make it valuable in various industries, but its toxicity requires careful handling and regulation. Testbourne provides high-quality cadmium products for scientific and industrial applications, ensuring safety and performance in all uses.
