  2. Beryllium - Wikipedia

    en.wikipedia.org/wiki/Beryllium

    Cross-rolled beryllium sheet is an excellent structural support for printed circuit boards in surface-mount technology. In critical electronic applications, beryllium is both a structural support and heat sink. The application also requires a coefficient of thermal expansion that is well matched to the alumina and polyimide-glass substrates.

  3. Beryllium copper - Wikipedia

    en.wikipedia.org/wiki/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 electricity. [2] It is used for its ductility, weldability in metalworking, and machining ...

  4. 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 ]

  5. Alkaline earth metal - Wikipedia

    en.wikipedia.org/wiki/Alkaline_earth_metal

    In electronics, beryllium is used as a p-type dopant in some semiconductors, [67] and beryllium oxide is used as a high-strength electrical insulator and heat conductor. [68] Beryllium alloys are used for mechanical parts when stiffness, light weight, and dimensional stability are required over a wide temperature range.

  6. E-Material - Wikipedia

    en.wikipedia.org/wiki/E-Material

    E-Material, also called E Material, is a metal matrix composite consisting of beryllium matrix with beryllium oxide particles. It has high thermal conductivity (210-230 W/m K), and its thermal expansion can be adjusted to match other materials, e.g. silicon and gallium arsenide chips and various ceramics.

  7. Rare-earth element - Wikipedia

    en.wikipedia.org/wiki/Rare-earth_element

    Compounds containing rare earths have diverse applications in electrical and electronic components, lasers, glass, magnetic materials, and industrial processes. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties, but have ...

  9. Lithium beryllide - Wikipedia

    en.wikipedia.org/wiki/Lithium_beryllide

    Lithium beryllide is a hypothetical intermetallic compound of lithium and beryllium that may have several possible compositions, including LiBe, LiBe 2, Li 2 Be, LiBe 3, Li 3 Be, Li 2 Be 3, Li 3 Be 2, LiBe 4 and Li 4 Be. [1] Computational methods indicate that some of these compositions may be superconductive under very high pressure and low ...
