PROBLEM TO BE SOLVED: To provide a long-sized plate-like oxygen sensor element which is made of a flat plate shape and which has excellent durability, heat resistance and stability without breaking the element in the case of operating for a long period of time.;SOLUTION: The oxygen sensor ...
PROBLEM TO BE SOLVED: To provide both a laminated-type oxygen sensor element superior in thermal shock resistance by forming the oxygen sensor element in the shape of a staircase with three steps or more and capable of uniformly holding a solid electrolyte heated by a heater at higher ...
Oxygen (O2) is the third-most abundant element by mass in the universe after hydrogen (H2) and helium (He). It is also the most abundant element by mass in the Earth’s crust.For living organisms, uptake of O2 from the air is the essential purpose of breathing. Oxygen plays a ...
Oxygen, O2, is a colorless, tasteless, gaseous element essential to almost all forms of life. It promotes respiration and combustion. Oxygen comprises 20% of the earth's atmosphere and is the most abundant element in seawater and in the earth's crust. It is slightly soluble in water and ...
Oxygen in bcc (β) titanium is an interstitial element. Oxygen increases the temperature range of stability of α and ωiso phases and stabilizes them by diffusion. On the other hand, interstitial oxygen atoms prevent the formation of ωath and α″ phases by displacive transformations. In all...

Production methods chosen for oxygen depend upon the quantity of the element desired. Laboratory procedures include the following: 1. Thermal decomposition of certain salts, such as potassium chlorate or potassium nitrate: The decomposition of potassium chlorate is catalyzed by oxides of transition metals...
