  2. Lithium oxide - Wikipedia

    en.wikipedia.org/wiki/Lithium_oxide

    Burning lithium metal produces lithium oxide. Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen at temperatures above 100 °C: [3] 4Li + O 2 → 2 Li 2 O. Pure Li 2 O can be produced by the thermal decomposition of lithium peroxide, Li 2 O 2, at 450 °C [3] [2] 2 Li ...

  3. High-temperature oxidation - Wikipedia

    en.wikipedia.org/wiki/High-temperature_oxidation

    High temperature oxidation is generally occurs via the following chemical reaction between oxygen (O 2) and a metal M: [2]. nM + 1/2kO 2 = M n O k. According to Wagner's theory of oxidation, oxidation rate is controlled by partial ionic and electronic conductivities of oxides and their dependence on the chemical potential of the metal or oxygen in the oxide.

  4. Lithium peroxide - Wikipedia

    en.wikipedia.org/wiki/Lithium_peroxide

    Lithium peroxide is the inorganic compound with the formula Li 2 O 2. Lithium peroxide is a white solid, and unlike most other alkali metal peroxides, it is nonhygroscopic . Because of its high oxygen:mass and oxygen:volume ratios, the solid has been used to remove CO 2 from and release O 2 to the atmosphere in spacecraft .

  5. Rapid thermal processing - Wikipedia

    en.wikipedia.org/wiki/Rapid_thermal_processing

    Rapid thermal processing (RTP) is a semiconductor manufacturing process which heats silicon wafers to temperatures exceeding 1,000°C for not more than a few seconds. During cooling wafer temperatures must be brought down slowly to prevent dislocations and wafer breakage due to thermal shock.

    Lithium hydroxide is another important compound that is used in air purification systems, as well as in the production of lithium greases and lubricants. Lithium chloride is used as a desiccant and in the production of lithium metal, while lithium sulfate is used in the production of fertilizers and as a reagent in chemical reactions

  7. Glass-to-metal seal - Wikipedia

    en.wikipedia.org/wiki/Glass-to-metal_seal

    Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...

  8. Thermal oxidation - Wikipedia

    en.wikipedia.org/wiki/Thermal_oxidation

    Thermal oxidation of silicon is usually performed at a temperature between 800 and 1200 °C, resulting in so called High Temperature Oxide layer (HTO). It may use either water vapor (usually UHP steam ) or molecular oxygen as the oxidant; it is consequently called either wet or dry oxidation.

  9. High-temperature corrosion - Wikipedia

    en.wikipedia.org/wiki/High-temperature_corrosion

    High-temperature corrosion is a mechanism of corrosion that takes place when gas turbines, diesel engines, furnaces or other machinery come in contact with hot gas containing certain contaminants. Fuel sometimes contains vanadium compounds or sulfates, which can form low melting point compounds during combustion.
