What Family Is Cobalt in on the Periodic Table

Cobalt Atomic Weight 58.933194 Density 8.9 g/cm 3 Melting Betoken 1495 °C Boiling Point 2927 °C Full technical data Cobalt is used in pigments, notably cobalt blue, and in loftier-strength, loftier-temperature steel alloys. Loftier purity cobalt is obtained by electrolyzing cobalt ions out of solution, resulting in bumpy plate like this. Scroll down to see examples of Cobalt.

I originally idea these were titanium, simply the source, Paul Wellin'south Blood brother, reports as follows:
"The tiptop of articulatio genus articulation and the hip joint ball attachment are probably fabricated of a different alloy, cobalt-chrome, for increased force and decreased flexibility as compared to titanium."

This is just crazy. When I first heard about these things my jaw literally dropped (not literally). They are obsolete now, having been hopelessly beaten by solid state flash memory, merely in their day they were the highest chapters compact retentivity cards available, up to 8GB past 2008 (by which time 64GB flash memory cards were available).
And they are mechanical hard disk drives. Let me remind you of the dimensions of a meaty wink bill of fare (type II): 1.4" x ane.7" ten 0.2" (36.4mm x 42.8mm x 5mm). The platter in this drive is near i" (2.5cm) in diameter. It's just crazy small. In that location's an electrical motor spinning the platter, an electro-magnet that moves the read-write heads back and forth, the whole works, plus of course all the control and interface electronics, packing into no space.
I stand in awe of this device.
The platters are aluminum, the electronics are silicon, the wiring is copper, the magnets are neodymium atomic number 26 boron, and the magnetic coating is atomic number 26 and cobalt based.

Exercise yous remember when manganese nodules were going to be the next great aureate rush? When a great new natural resources was going to exist unleashed simply every bit before long every bit someone figured out how to dredge them up from the incredibly deep bounding main? Did you lot e'er wonder if there might not be some in shallower h2o?
Well, judge what: The whole thing was a consummate fabrication. The CIA wanted to recover a Soviet submarine that had gone down in very, very deep water in the Pacific, and they needed a cover story because they knew that there was no style they could build and deploy the highly specialized kind of transport required to recover something from such keen depth without the Russians (who knew exactly where their submarine had gone downwardly) figuring out that something was up.
And so they enlisted Howard Hughes, the richest human being in the earth at the time and a notable nutcase, to pretend that he thought these manganese nodules, which just happened to exist only at great depths, were the side by side big thing. He built a big, specialized deep sea recovery ship, the Glomar Explorer, and sent it to detect, um, um, manganese nodules, that'south right, we're looking for manganese nodules.
They actually did observe the Soviet submarine and were able to recover parts of it. Somewhen people forgot about the manganese nodules.
If you don't believe me, read this report on the subject:
http://www.fas.org/irp/programme/collect/jennifer.htm
This detail nodule was recovered from 5100m of water in the central pacific by the MS Valdiva working for the Metallgesellschaft AG, Frankfurt am Primary. I wonder if they thought they were going to get rich.
