4. Conclusions. Tantalum nitride films were deposited on ceramic substrates (pre-sputtered with underlayer and 100-nm-thick aluminum oxide) by DC reactive magnetron sputtering using a Ta target under a typical base pressure of 10 â7 Torr.
Earth's atmosphere is a thin blanket of gases and tiny particlesâtogether called air. Without air, the Earth would just be another lifeless rock orbiting the Sun. Although we are rarely aware of it, air surrounds us. We are most aware of air when it moves, creating wind.
What are the four main gases in the atmosphere? Answer The Earth's atmosphere contains roughly by volume: 78.08% nitrogen 20.95% oxygen 0.93% argon 0.038% carbon dioxide and trace amounts of other gases, and a variable amou â¦ nt of water vapor.he main three gases in air are nitrogen, oxygen and inert gases 78% of air is made up of nitrogen, 21% is oxygen, just under 1% is argon and the remaining part is made up o â¦ f other gases such as carbon dioxide and water vapour. + 9 others found this useful.
