  2. Boron group - Wikipedia

    en.wikipedia.org/wiki/Boron_group

    The elements in group 13 are also capable of forming stable compounds with the halogens, usually with the formula MX 3 (where M is a boron-group element and X is a halogen.) [14] Fluorine, the first halogen, is able to form stable compounds with every element that has been tested (except neon and helium), [15] and the boron group is no exception.

  3. Boron - Wikipedia

    en.wikipedia.org/wiki/Boron

    Boron carbide and cubic boron nitride powders are widely used as abrasives. Boron nitride is a material isoelectronic to carbon . Similar to carbon, it has both hexagonal (soft graphite-like h-BN) and cubic (hard, diamond-like c-BN) forms. h-BN is used as a high temperature component and lubricant. c-BN, also known under commercial name borazon ...

  4. Boride - Wikipedia

    en.wikipedia.org/wiki/Boride

    The main group metals, lanthanides and actinides form a wide variety of boron-rich borides, with metal:boron ratios up to YB 66. The properties of this group vary from one compound to the next, and include examples of compounds that are semi conductors, superconductors, diamagnetic, paramagnetic, ferromagnetic or anti-ferromagnetic.

    en.wikipedia.org/wiki/List_of_semiconductor...

    A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).

  6. Boron compounds - Wikipedia

    en.wikipedia.org/wiki/Boron_compounds

    Boron (III) trifluoride structure, showing "empty" boron p orbital in pi-type coordinate covalent bonds. Boron compounds are compounds containing the element boron. In the most familiar compounds, boron has the formal oxidation state +3. These include oxides, sulfides, nitrides, and halides. [1]

  7. Boron nitride - Wikipedia

    en.wikipedia.org/wiki/Boron_nitride

    Boron nitride (along with Si 3 N 4, NbN, and BNC) is generally considered to be non-toxic and does not exhibit chemical activity in biological systems. [107] Due to its excellent safety profile and lubricious properties, boron nitride finds widespread use in various applications, including cosmetics and food processing equipment. [108] [109]

  8. Tourmaline - Wikipedia

    en.wikipedia.org/wiki/Tourmaline

    Tourmaline (/ ˈ t ʊər m ə l ɪ n,-ˌ l iː n / TOOR-mə-lin, -⁠leen) is a crystalline silicate mineral group in which boron is compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. This gemstone comes in a wide variety of colors.

  9. Group (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Group_(periodic_table)

    In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.
