High Quality Content by WIKIPEDIA articles! Suntan was the code-name of a prototype reconnaissance aircraft program, with the goal of creating a much faster and higher-altitude successor to the U-2, enabled by the use of liquid hydrogen (LH2) as fuel. From 1956-1958, the United States Air Force funded a highly secretive program of research and development on the aircraft (the CL-400, designed at the Lockheed Skunk Works) and engine design, and made significant investments in large-scale LH2 production. In addition to Lockheed, Pratt and Whitney played a major part. Program successes included the concept design of a Mach 2.5 aircraft capable of flying at 30,000 meters, and successful conversion of an existing turbojet engine to run on...

High Quality Content by WIKIPEDIA articles! Magnesium silicide, Mg2Si, is an inorganic compound consisting of magnesium and silicon. As a powder magnesium silicide is dark blue or slightly purple in color. Silicon dioxide, SiO2, found in sand and glass, when heated with magnesium forms magnesium oxide, and, if an excess of magnesium is used, magnesium silicide is formed. The first product in this reaction is silicon, which then reacts further with magnesium to produce Mg2Si. The stoichiometry of these reactions are such that with a 2:1 Mg:SiO2 molar ratio, MgO is formed:
