Density at K: 8. The tomb of Pharaoh Tutankhamen, who ruled from BC, contained a small glass object coloured deep blue with cobalt. Cobalt blue was known even earlier in China and was used for pottery glazes. In , chemist Georg Brandt of Stockholm became interested in a dark blue ore from some local copper workings and he eventually proved that it contained a hitherto unrecognised metal and he gave it the name by which its ore was cursed by miners in Germany, where it was sometimes mistaken for a silver ore. He published his results in

Nickel, Chromium, Cobalt Dental Alloys and Allergic Reactions an Overview

Cobalt is a chemical element with the symbol Co and atomic number Like nickel , cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element , produced by reductive smelting , is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments cobalt blue have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was later thought to be due to the known metal bismuth. Miners had long used the name kobold ore German for goblin ore for some of the blue-pigment-producing minerals ; they were so named because they were poor in known metals, and gave poisonous arsenic -containing fumes when smelted. In , such ores were found to be reducible to a new metal the first discovered since ancient times , and this was ultimately named for the kobold. Today, some cobalt is produced specifically from one of a number of metallic-lustered ores, such as cobaltite CoAsS.

Havar (alloy)

Havar , or UNS R , is an alloy of cobalt , possessing very high mechanical strength. It can be heat-treated. It is highly resistant to corrosion and is non- magnetic.

Superalloys: Properties, Processing, and Applications

This is a list of named alloys grouped alphabetically by base metal. Within these headings, the alloys are also grouped alphabetically. Some of the main alloying elements are optionally listed after the alloy names.

 Выходит, все в порядке. - Это лишь означает, - сказала она, пожимая плечами, - что сегодня мы не взломали ни одного шифра. ТРАНСТЕКСТ устроил себе перерыв.

Он в последний раз бросил взгляд на труп на алюминиевой столешнице. Покойный лежал на спине, лицом вверх, освещаемый лампами дневного света, вроде бы ничего не скрывая. Беккер непроизвольно снова и снова вглядывался в его странно деформированные руки. Он присмотрелся внимательнее. Офицер выключил свет, и комната погрузилась в темноту.

Беккер еще раз обвел глазами кучу вещей и нахмурился. Зачем АНБ вся эта рухлядь. Вернулся лейтенант с маленькой коробкой в руке, и Беккер начал складывать в нее вещи. Лейтенант дотронулся до ноги покойного. - Quien es.

И уже мгновение спустя ее осенило. Ее глаза расширились.
