  2. Transparent ceramics - Wikipedia

    en.wikipedia.org/wiki/Transparent_ceramics

    It has all the workability of an amorphous glass, but upon recrystallization it demonstrates properties similar to a crystalline ceramic. Vycor is 96% fused silica glass, which is crystal clear, lightweight and high strength. One advantage of these type of materials is that they can be produced in large sheets and other curved shapes. [23] [24]

  3. 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.

  4. 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.

  5. 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.

  6. 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. Cristallo - Wikipedia

    en.wikipedia.org/wiki/Cristallo

    Cristallo is a glass that is totally clear (like rock crystal), without the slight yellow or greenish color originating from iron oxide impurities. This effect is achieved through small additions of manganese oxide. [1] Cristallo often has a low lime content, which makes it prone to glass corrosion (otherwise known as glass disease).

  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.
