Tantalum Tantalum is a shiny‚ silvery metal which is soft when is pure. It is almost immune to chemical attack at temperatures below 150 C. Tantalum is virtually resistant to corrosion due to an oxide film on its surface. Applications Tantalum finds use in four areas: high-temperature applications‚ such as aircraft engines; electrical devices‚ such as capacitors; sirurgical impants and handling corrosive chemicals. It is rarely used as an alloying agent because it tends to make metals brittle

has been done in the port when water levels were low and docks have been moved or extended for access by boats. Large ore docks have already been removed from the Chequamegon Bay due in part to environmental damage. My father used to work on the large ore boats on the great lakes. We would go see one of these docks that were located next to the city of Ashland on the bay. The ore dock was a massive structure that seemed indestructible‚ especially by water levels rising or lowering.

surveyor of mining‚ Müller’s task was to analyze several different ore samples. In 1782 while viewing a gold ore‚ he soon discovered the chemical element‚ Tellurium. After analyzing the ore‚ Müller first came to the conclusion that it was Antinomy alloyed in there‚ but quickly realized it wasn’t. “The metal he had produced wasn’t antimony at all‚ but a previously unknown element.”(Steven Gagnon) Because tellurium is found in various ores and contains the same properties as metals and nonmetals‚ it confused
