  2. Glass-ceramic - Wikipedia

    en.wikipedia.org/wiki/Glass-ceramic

    The crystal growth process is of considerable importance in determining the morphology of the produced glass ceramic composite material. Crystal growth is primarily dependent on two factors. First, it is dependent upon the rate at which the disordered structure can be re-arranged into a periodic lattice with longer-range order.

  3. Prince Rupert's drop - Wikipedia

    en.wikipedia.org/wiki/Prince_Rupert's_drop

    Prince Rupert's drops. Prince Rupert's drops (also known as Dutch tears or Batavian tears) [1] [2] are toughened glass beads created by dripping molten glass into cold water, which causes it to solidify into a tadpole-shaped droplet with a long, thin tail.

  4. Transparent ceramics - Wikipedia

    en.wikipedia.org/wiki/Transparent_ceramics

    Synthetic sapphire – single-crystal aluminum oxide (sapphire – Al 2 O 3) is a transparent ceramic Transparent ceramics have recently acquired a high degree of interest and notoriety. Basic applications include lasers and cutting tools, transparent armor windows, night vision devices (NVD), and nose cones for heat seeking missiles.

  5. Aluminium oxynitride - Wikipedia

    en.wikipedia.org/wiki/Aluminium_oxynitride

    Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen.Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet, visible, and mid-wave-infrared regions of the electromagnetic spectrum.

  6. Lead glass - Wikipedia

    en.wikipedia.org/wiki/Lead_glass

    Cut glass wine glass made of lead glass. Lead glass, commonly called crystal, is a variety of glass in which lead replaces the calcium content of a typical potash glass. [1] Lead glass contains typically 18–40% (by mass) lead(II) oxide (PbO), while modern lead crystal, historically also known as flint glass due to the original silica source, contains a minimum of 24% PbO.

  7. Vitrification - Wikipedia

    en.wikipedia.org/wiki/Vitrification

    It prevents ice crystal formation and is a very fast process: -23,000 °C/min. Currently, vitrification techniques have only been applied to brains ( neurovitrification ) by Alcor and to the upper body by the Cryonics Institute , but research is in progress by both organizations to apply vitrification to the whole body.

  8. Crazing - Wikipedia

    en.wikipedia.org/wiki/Crazing

    Consequently, a stressed material with a high density of crazes may appear 'stress-whitened,' as the scattering makes a normally clear material become opaque. [ 6 ] Crazing is a phenomenon typical of glassy amorphous polymers , [ 7 ] but can also be observed in semicrystalline polymers .

  9. Frit - Wikipedia

    en.wikipedia.org/wiki/Frit

    Frit. A frit is a ceramic composition that has been fused, quenched, and granulated.Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides.
