  2. Beryllium copper - Wikipedia

    en.wikipedia.org/wiki/Beryllium_copper

    Adjustable Wrench with 'BeCu' on the side, to show that it is made from beryllium copper. Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze, and spring copper, is a copper alloy with 0.5–3% beryllium. [1] Copper beryllium alloys are often used because of their high strength and good conductivity of both heat and ...

    The most famous ReBCO is yttrium barium copper oxide, YBa 2 Cu 3 O 7−x (or Y123), the first superconductor found with a critical temperature above the boiling point of liquid nitrogen. [10] Its molar ratio is 1 to 2 to 3 for yttrium, barium, and copper and it has a unit cell consisting of subunits, which is the typical structure of perovskites .

    Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds that display high-temperature superconductivity; it includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen [77 K (−196.2 °C; −321.1 °F)] at about 93 K (−180.2 °C; −292.3 °F).

  9. Beryllium oxide - Wikipedia

    en.wikipedia.org/wiki/Beryllium_oxide

    Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is an electrical insulator with a higher thermal conductivity than any other non-metal except diamond , and exceeds that of most metals. [ 12 ]
