Cobalt vs Hague

Informations

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in 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 1735, 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). The element is, however, more usually produced as a by-product of copper and nickel mining.

The copper belt in the Democratic Republic of the Congo (DRC) and Zambia yields most of the global cobalt production. World production in 2016 was 116,000 metric tons (114,000 long tons; 128,000 short tons) (according to Natural Resources Canada), and the DRC alone accounted for more than 50%.Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys. The compounds cobalt silicate and cobalt(II) aluminate (CoAl2O4, cobalt blue) give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. Cobalt occurs naturally as only one stable isotope, cobalt-59. Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high-energy gamma rays. Cobalt is the active center of a group of coenzymes called cobalamins. Vitamin B12, the best-known example of the type, is an essential vitamin for all animals. Cobalt in inorganic form is also a micronutrient for bacteria, algae, and fungi.

The Hague (; Dutch: Den Haag [dɛn ˈɦaːx] (listen) or 's‑Gravenhage [ˌsxraːvə(n)ˈɦaːɣə] (listen)) is a city on the western coast of the Netherlands on the North Sea, the administrative and royal capital of the Netherlands and the capital of the province of South Holland. It is also the seat of government of the Netherlands and hosts the International Court of Justice, one of the most important courts in the world. With a metropolitan population of more than 1 million, it is the third-largest city in the Netherlands, after Amsterdam and Rotterdam. The Rotterdam–The Hague metropolitan area, with a population of approximately 2.7 million, is the 10th-largest in the European Union and the most populous in the country. In the west of the Netherlands, The Hague is in the centre of the Haaglanden conurbation and lies at the southwest corner of the larger Randstad conurbation.

The Hague is the seat of the Cabinet, the States General, the Supreme Court, and the Council of State of the Netherlands, but the city is not the constitutional capital of the Netherlands, which is Amsterdam. King Willem-Alexander lives in Huis ten Bosch and works at the Noordeinde Palace in The Hague, together with Queen Máxima. Most foreign embassies in the Netherlands are located in the city. The Hague is also home to the world headquarters of Royal Dutch Shell and other Dutch companies. The Hague is known as the home of international law and arbitration. The International Court of Justice, the main judicial arm of the United Nations, is located in the city, as well as the International Criminal Court, the Permanent Court of Arbitration, Europol, and approximately 200 other international governmental organisations.
