  • Electrochemistry Encyclopedia -- Space resource

    The main component of Anorthositic Lunar Highland Soil is a mixed oxide of calcium, silicon, and aluminum (anorthite, CaSi 2 Al 2 O 8).It can be dissolved in a fluoride-containing melt, similar to aluminum oxide in a cryolitic melt in conventional industrial aluminum production.Oxygen can be evolved at suitable anodes, as they are being developed also for terrestrial aluminum production.

  • Oxid Article about Oxid by The Free Dictionary

    Carbon monoxide, sulfur dioxide, and oxides of nitrogen are among the waste gases of gasoline-burning internal-combustion engines. Nitrous oxide is an oxide of nitrogen often called laughing gas. Many of the metals form oxides. Some metal oxides, e.g., those of iron, aluminum, tin, and zinc, are important as ores.
