  what is cobalt wanted for?

Cobalt has many uses for its compounds. First, it has been used for distinctive and attractive color to glass objects. Blue is the most well known shade, but pink and green are also present in glass coloring. The element is also a powerful gamma ray emitter used for radio therapy, leak detection in pipes, and irradiating food to kill bacteria. A gamma ray is a high energy electromagnetic radiation given off by some nuclei. Only some food-processing plants use radiation from Co 60 to kill bacteria in foods. Cobalt Is a very useful radioactive isotope. Cobalt can make various alloys with other metals. When mixed with Iron, Cobalt can produce high temperature steel. With Aluminum and Nickel, it is used in magnets. Carbon and Tungsten, or Chromium and Iron, mixed with Cobalt can formulate hard alloys for drill bits and cutting tools. With those same elements, Cobalt can withstand high temperatures used in gas turbines and jet engines. It is also used in cobalt magnets, MRI machines, electronic devices, and speakers with Aluminum, Nickel, and Iron. Cobalt occurs in the minerals Cobaltite, Smaltite, and Erythirite and is associated with Nickel, Silver, Lead, Copper, and Iron ores. Some other uses include; dental and surgical applications, Catalysts, and Cobalt boats. Catalysts are substances that increase the speed of chemical reaction without being consumed by the reaction. Cobalt is also present in meteorites.

  when was the elemnet of cobalt invented

It wasnt invented but it was discovered in 1735 by george brant in stockholm swedan, but it was named after German miners. Kobald= goblin in german.

(3)The word cobalt is derived from the erman Kobalt from Kobold meaning Goblin.

(4)Cobalt 60 is used in cancer therapy. It is a gamma ray source.

I hope that helped alot i did this for science to get a better mark and i did well hope that help.

thank you very much this helps me exactly for what i am doing in my science project thank you!

Hi, I'm learning about the periodic table and i have chosen the element cobalt and i wanted to know what family does it belong to. i know its classified as a metal bascially every site i went to it doesn't tell me what family it belongs to...so what is the family. Also i would like to know some interesting facts,common compounds, and its important uses. i thank you for taking the time to read my letter.

From,Adrian
