Sorry, no etymologies found.


  • If it may be assumed that the other silicides in commercial calcium carbide also behave in this manner it is plain that hydrogen silicide cannot occur in crude acetylene unless the gas is supposed to be hurried out of the generator before the alkaline water therein has had time to decompose any traces of the hydrogen silicide which is produced in the favouring conditions of high temperature sometimes prevailing.

    Acetylene, the Principles of Its Generation and Use

  • Fuel is uranium aluminium silicide with enrichment levels of up to 20%, giving up to 4-year refuelling intervals.

    Small nuclear power reactors

  • To late 2004, 38 research reactors (11 in USA) either have been or are being converted to low-enriched uranium silicide fuel, and another 36 are convertible using present fuels. 31 more, mostly Russian designs, need higher-density fuels not yet available.

    Research reactors

  • There have been successful tests with denser U3Si-Al fuel plates up to 6.1 g/cm3, but US development of these silicide fuels ceased in 1989 and did not recommence until 1996.

    Research reactors

  • This development work has been undertaken to provide fuels that can extend the use of LEU to those reactors requiring higher densities than available in silicide dispersions and to provide a fuel that can be more easily reprocessed than the silicide type.

    Research reactors

  • The first generation of new LEU fuels used uranium (U) and silicon (Si) (U3Si2-Al — uranium silicide dispersed in aluminium), at 4.8 g/cm3.

    Research reactors

  • Dave Lang, silicide Schottky barriers from Marty Lepselter through Jim Phillips, infrared spectroscopy of shallow donors and acceptors from Gordon Thomas, and transport in the 2-dimensional electron gas from Dan Tsui.

    Robert B. Laughlin - Autobiography

  • Ferrosilicon is a silicide of iron alloyed with an excess of iron, which finds extensive use in the manufacture of certain kinds of steel.

    An Elementary Study of Chemistry

  • Boussingault has shown that this is due to the formation of a silicide of platinum by means of the reduction of the silica of the carbon by the metal.

    Scientific American Supplement, No. 365, December 30, 1882

  • Caro has seen one specimen of (bad) carbide which gave a spontaneously inflammable gas although it contained only traces of phosphine; its inflammability being caused by 2.1 per cent. of hydrogen silicide.
