Cobalt is a transition metal, similar in properties to adjacent metals Fe and Ni ( Figure 1). It occurs in the +2 and +3 oxidation states, can substitute for Fe in ferromagnesian rocks and ...

As allochromatic gemstones, spinels get their color from trace elements. For years, gemologists thought the same iron-to-iron interaction that results in darker, greenish blue body colors in spinels also caused vivid blue hues. However, in 1984, scientists first identified cobalt as an additional coloring agent for highly saturated blue spinels ...

The high-quality construction also makes these bits ideal for drilling through hard steels like stainless steel, titanium alloys, and even hardened metals.When you need precision accuracy for your drilling jobs, ½-inch cobalt drill bits deliver the power and results you need to get the job done right.

Combining cobalt MRR, polished surface quality, and oxidation film thickness shown in Fig. 5, Fig. 6, Fig. 9, Fig. 10, when the applied voltage is 0–2 V, the oxidation film becomes thicker and the mechanical force can remove nearly all film simultaneously. Thus, cobalt MRR rises and the polished surface is better.

High-quality Co films with low resistivity (10 μΩ cm) were deposited by plasma-enhanced atomic layer deposition (PE-ALD) from metallorganic precursors and NH 3 plasma. The deposition characteristics and film properties were investigated. Especially, we compared the results using two cyclopentadienyl Co precursors, CoCp(CO) 2 and …

Those effects can include breathing problems, birth defects, and death. One study discovered that the urine of adult residents near mines had cobalt concentrations forty-three times higher than the urine of a control group and lead levels five times higher (Frankel, 2016). For children, these numbers were worse.
