whats the meaning silicon carbide in alaska

FAQs - Frequently Asked Questions about Silicon …

Silicon carbide, often referred to by its chemical formula, SiC, is a synthetically produced crystalline compound consisting of silicon and carbon. Due to its exceptional abrasive properties, SiC was the first synthetic abrasive to be produced and has been in use since the late 19th century, in appliions ranging from sandpaper to grinding wheels and cutting tools.

The Enhanced Greenhouse Effect and Global …

The theory behind the enhanced greenhouse effect is that human activities can load the atmosphere with too much carbon dioxide and other heat-trapping gases. This could increase Earth''s temperature above that expected from the natural greenhouse effect, an effect known as global warming.

Argon - Wikipedia

Argon is a chemical element with the syol Ar and atomic nuer 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in the Earth''s atmosphere, at 0.934% (9340 ppmv).It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as
