Solid oxygen O 2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum. Oxygen molecules have attracted attention because of the relationship between the molecular magnetization and crystal structures , electronic structures , and superconductivity .
4) was discovered in 2001, [45] [46] and was assumed to exist in one of the six phases of solid oxygen. It was proven in 2006 that this phase, created by pressurizing O 2 to 20 GPa, is in fact a rhombohedral O 8 cluster. [47] This cluster has the potential to be a much more powerful oxidizer than either O 2 or O 3 and may therefore be used in ...
There are six known distinct phases of solid oxygen. One of them is a dark-red O 8 cluster. When oxygen is subjected to a pressure of 96 GPa, it becomes metallic , in a similar manner to hydrogen , [ 14 ] and becomes more similar to the heavier chalcogens , such as selenium (exhibiting a pink-red color in its elemental state), tellurium and ...
The Vika oxygen generating system, used on Mir and later the International Space Station under the NASA designation Solid Fuel Oxygen Generator (SFOG) is based on lithium perchlorate, which releases about 60% of its weight in oxygen. Of all the perchlorates, lithium perchlorate has both the highest oxygen to weight and oxygen to volume ratio ...
Although solid magnesium reacts slowly with oxygen at STP, it is capable of burning in air, generating very high temperatures, and its metal powder may form explosive mixtures with air. Oxygen is present as compounds in the atmosphere in trace quantities in the form of carbon dioxide (CO 2) and oxides of nitrogen (NO x).
Vika or TGK is an oxygen generating system for spaceflight. [1] It is a SFOG, or solid-fuel oxygen generator, a kind of chemical oxygen generator. [1] It has been used on the retired Mir space station and the International Space Station. [1] It was originally developed by Roscosmos to supplement the Elektron oxygen system on Mir. [1]
A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture. The mixture has an indefinite ...
Octaoxygen, also known as ε-oxygen or red oxygen, is an allotrope of oxygen consisting of eight oxygen atoms. This allotrope forms at room temperature at pressures between 10 and 96 GPa. This allotrope forms at room temperature at pressures between 10 and 96 GPa.
