Who invented carbide?
Thomas “Carbide” Wilson: Prolific Inventor and Father of Carbide. This article was originally written and submitted as part of a Canada 150 Project, the Innovation Storybook, to crowdsource stories of Canadian innovation with partners across Canada.
Where is tungsten carbide from?
Approximately 85% of the world’s tungsten comes from China and is extracted from various ores. Tungsten ore is refined to form tungsten oxide or pure tungsten powder. The process to combine tungsten metal with carbon to form tungsten carbide (abbrev. WC) can be accomplished several different ways.

Who invented acetylene gas?
Acetylene was discovered in 1836, when Edmund Davy was experimenting with potassium carbide. One of his chemical reactions produced a flammable gas, which is now known as acetylene.
When was calcium carbide invented?
On May 2, 1892, in Spray (now Eden), Canadian chemist Thomas L. Willson accidentally produced calcium carbide and acetylene with an electric-arc furnace. In August, Willson applied for a patent for the new process.
What Colour is tungsten carbide?
deep gray
Tungsten carbide is the result of combining or alloying carbon with tungsten, hard and dense metal with a high melting point. Tungsten carbide is a deep gray color in its untreated, natural state, but it can be polished, sandblasted, or carved to give it a wide range of finishing aesthetics.

Who discovered tungsten year?
In 1750, this heavy mineral was discovered in the Bispberg´s iron mine in the Swedish province Dalecarlia. The first person who mentioned the mineral was Axel Frederik Cronstedt in 1757, who called it Tungsten {composed of the two Swedish words tung (heavy) and sten (stone)} due to its density close to 6.

Rhenium/Discoverers
Rhenium-molybdenum alloys are superconductive at 10 K. Rhenium was discovered in 1925 by Walter Noddack, Ida Noddack-Tacke, and Otto Berg in Germany in platinum ores, such as columbite and tung-state.
