The Growth Of Metallurgy

Main

Zinc

1400

Zinc was known as a Chinese element. William Champion was the one who out zinc in the distillation process in the year 1738. The Indian Tin or Pewter was known to have zinc before china. In 1781 brass was made by adding zinc to cooper in a liquid form.

Platinum

1500

Platinum was not 100% pure. Platinum was banned because people was using it to make blank coins.

Antimony

1560

Antimony was formed by stibium or antimony sulphide being roasted into a iron pot. Antimony comes from a Greek analogy " anti plus mono's"- a metal not found alone. Antimony is a extremely brittle flaky metal. Antimony was initial was used as an alloy for lead when it increased its hardness.

Bismuth

1595

Bismuth was in reproduction in the year 1595 but it was not classified as a element till the year 1753. This element was used for the reproduction of oxide with carbon.

Arsenic

1641

Arsenic was created by Albertus Magnus. Arsenic when heated twice is weighs as much as soap. Arsenic is steel gray and brittle. This metal tarnishes in the open air. During the Bronzing production arsenic is used.

Several metals were isolated

1700

Cobalt, Nickel, Manganese, Molybdenum, Tungsten, Tellurium, Beryllium , Chromium,
Uranium, Zirconium and Yttrium . These elements were produced by laboratories only. They were all produced by carbon with the exception of tungsten.

cobalt

1735

Zinc

1738

it was known to the Chinese in 1400; however , it was not until 1738, when William Champion patented the zinc distillation process, that zinc came into common use.

nickel

1751

Magnanese

1774

molybdenum

1781

Tellurium

1782

Tungsten

1783

Uranium and zirconium

1789

Beryllium and chrimium

1791

Titamium

1791

Yttrium

1794

platinum

1800

although not 100% pure, it was the first metal to be discovered and sourced from the "New World". The property which brought this metal to the prospectors attention was its lack of reactivity with known reagents. Early use of platinum was banned because it was used as a blank for coins which were gold coated, proving that the early metallugists understood not only density but also economics.

Potassium and sodium

1807

Sir Humphery Davy Used these elements to generate the pile by developing the Volta and demonstrated that water could be decomposed into hydrogen and
oxygen .

Charles Askins

1817

Charles Askins developed a method to separate cobalt and nickel by using bleaching powder.

Cadmium

1817

Stroymeyer announced that Cadmium has a lower boiling point then Zinc so cadmium was distilled first.

Cadmium

1817

Stroymeyer noted that Zinc carbonate had a yellowish tinge not attributable to iron. Upon reduction he thought that the alloy contained two metals. The metals were separated by fractional distillation. At 800 C, as cadmium's boiling point is lower than Zinc, the cadmium distilled first.

Aluminum

1825

Aluminum was produced by Christian Oersted. Quantities were not produced till 20 years later.

Beryllium

1828

Wohler produced beryllium by reducing beryllium chloride with potassium.

Chromium

1859

Chromium was produced by the reproduction of carbon.
