  2. Beryllium-aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/Beryllium-aluminium_alloy

    Beryllium-aluminum alloy an alloy that consists of 62% beryllium and 38% aluminum, by weight, corresponding approximately to an empirical formula of Be 2 Al. It was first developed in the 1960s by the Lockheed Missiles and Space Company, who called it Lockalloy, [1] [2] and used as a structural metal in the aerospace industry because of its high specific strength [3] and stiffness.

    en.wikipedia.org/wiki/Aluminium_compounds

    Aluminium's electropositive behavior, high affinity for oxygen, and highly negative standard electrode potential are all more similar to those of scandium, yttrium, lanthanum, and actinium, which have ds 2 configurations of three valence electrons outside a noble gas core: aluminium is the most electropositive metal in its group. [1]

    en.wikipedia.org/wiki/Aluminium

    Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.

    en.wikipedia.org/wiki/Aluminium(I)_compounds

    AlCl is synthesized by reaction of liquid aluminium with gaseous HCl at 1200 K and 0.2 mbar to yield gaseous AlCl and hydrogen gas. [1] At 77 K, AlCl is a dark red solid which turns black upon disproportionation at temperatures higher than 180 K.

  7. Lifting gas - Wikipedia

    en.wikipedia.org/wiki/Lifting_gas

    A lifting gas or lighter-than-air gas is a gas that has a density lower than normal atmospheric gases and rises above them as a result, making it useful in lifting lighter-than-air aircraft. Only certain lighter than air gases are suitable as lifting gases.

  8. Gas cylinder - Wikipedia

    en.wikipedia.org/wiki/Gas_cylinder

    A gas cylinder is used to store gas or liquefied gas at pressures above normal atmospheric pressure. [2] In South Africa, a gas storage cylinder implies a refillable transportable container with a water capacity volume of up to 150 litres. Refillable transportable cylindrical containers from 150 to 3,000 litres water capacity are referred to as ...
