Helium, Chemical Element - structure, uses, elements

Helium is a colorless, odorless, tasteless gas. It has a number of unusual properties. For example, it has the lowest boiling point of any element, -268.9°C (-452.0°F). The boiling point for a gas is the temperature at which the gas changes to a liquid. The freezing point of helium is -272.2°C (-458.0°F).

    Sodium nitrate NaNO3 - PubChem

    Jun 09, 2018 · The major concern of possible long-term effects of exposure to nitrate and nitrite is associated with formation of nitroso compounds, many of which are carcinogenic. This formation may take place wherever nitrite and nitrosable compounds are present, but it is favored by acidic conditions or the presence of some bacteria. Sodium nitrite NaNO2 - PubChemSodium nitrite is sold as the salt and in solution. The finely crystalline, slightly yellowish salt is marketed in untreated form and also after treatment with aryl alkyl sulfonates. The salt contains ca. 99.0 % sodium nitrite, 0.6 % sodium nitrate, < 0.1 % sodium chloride and sodium sulfate, and < 0.1 % water.

    Superheating in coated niobium - IOPscience

    Using muon spin rotation it is shown that the field of first flux penetration in Nb is enhanced by about 30% if coated with an overlayer of Nb 3 Sn or MgB 2.This is consistent with an increase from the lower critical magnetic field up to the superheating field of the Nb substrate. In the experiments presented here coatings of Nb 3 Sn and MgB 2 with a thickness between 50 and 2000 nm have been The chemical elements of the periodic table sorted by Chemical elements listed by boiling point The elemenents of the periodic table sorted by boiling point. click on any element's name for further chemical properties, environmental data or health effects..

This list contains the 118 elements of chemistry.Heat Treating of ium and ium AlloysNitrogen and carbon are also stabilizers, but these elements usually are not added intentionally in alloy formulation. Beta stabilizers, such as manganese, chromium, iron, molybdenum, vanadium, and niobium, lower the -to- transformation temperature and, depending on the amount added, may result in the retention of some phase at room temperature.
