What kind of metal is cobalt

It is widely applied in fields including aerospace, electronic appliances, machinery manufacturing, automobiles, chemical industry, agriculture, ceramics, etc. An important fact to note is that lithium-ion batteries used in electric vehicles are estimated to experience the largest increase in consumption of battery-used cobalt.

Global production volume of electric vehicles grew exponentially in recent years, with a growth rate far higher than that of traditional automobiles.

As the major raw material for electric vehicles, cobalt is expected to boast rapid growth. Moreover, power batteries account for the largest proportion in the downstream application of cobalt. Though cobalt is often bucketed into the general conflict minerals conversation, cobalt carries unique characteristics that differentiate it from the rest of the 3TG minerals.

It is usually combined with iron to form different alloys in many applications. Cobalt is a ferromagnetic material, hard yet brittle. It has a high melting point and is hard-wearing at elevated temperatures. It has high strength and possesses good conduction properties. Below are some key properties of cobalt [1,2]:.

The most popular is cobalt with a half-life of 5. Cobalt occurs typically in nature in cobaltite, smaltite, and erythrite minerals. It is mined along with nickel, silver , lead, copper , and iron ore and is often obtained as a by-product. The extraction of cobalt can be done using solvent extraction [4]. This reduces nickel and iron to ferronickel, and the cobalt and copper to a metallic state.

Cobalt has been used in many industrial, commercial, and military applications [5]. Below are some of its common applications:. Cobalt-based superalloys form high-temperature resistant parts for gas turbine aircraft engines, space vehicles, rocket motors, and other aerospace applications. Cobalt-based superalloys have a higher melting point than iron or nickel, and have excellent resistance to hot corrosion and thermal fatigue.

The weldability of this superalloy is also better than nickel superalloys. Altogether, cobalt-based superalloys perform exceptionally in applications with low stress and elevated temperature environments [6]. Cobalt steel is a variation of high-speed steel with common grades M and M It is an ideal cutting tool for its high red hardness that in turn provides high heat resistance. The cobaltic high-speed steel is able to run and withstand high feed rates and faster speed [7].

Cobalt is used widely as one of the metals needed to create hard permanent magnets with high coercivity, such as the aluminium-nickel-cobalt Al-Ni-Co alloy series. Alnico magnets are used in motors, hard disk drives, and sensors. Magnetic resonance imaging is an example of an application for these magnetic alloys. Cobalt oxide, hydroxide, and metals are used in many electrochemical devices that convert chemical energy to electrical energy, such as rechargeable batteries.

Portable devices such as mobile phones, laptops, and other consumer electronic devices right up to electric vehicles, all utilise rechargeable batteries. The supernova emitted about 60 percent of the sun's mass in cobalt, the researchers reported in the journal Nature. The isotope has a half-life of 77 days and gradually decays into iron Though still used in pigments, cobalt plays a variety of roles in modern technology. In September , researchers in Denmark reported that they'd created a crystalline material that can draw oxygen from air, store it, and then release it as needed.

Just 2. Just as iron is an essential ingredient in hemoglobin, the blood protein that snags oxygen from the lungs, cobalt is a key portion of this new material.

If oxygen-slurping cobalt weren't odd enough, a group of American researchers are working to integrate the metal into the food-safety process. Today, foods are tested for dangerous bacteria with a labor-intensive process that involves taking a sample, isolating and culturing any bacteria and waiting for them to grow. During this time, the batch of food being tested has to sit on the shelf — a particularly big problem for fresh fruits and vegetables. Now, Sam Nugen, a food scientist at the University of Massachusetts, Amherst, hopes to come up with a better solution.

Nugen and his team have developed a way to attach cobalt-iron nanoparticles to bacteriophages, or viruses that infect bacteria. The phages lock on to specific bacteria, such as E.
