    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.

    In addition, its low heat retention and low specific heat make it widely used in grinding operations, particularly cutoff tools. As the powdery abrasive mineral aloxite, it is a major component, along with silica, of the cue tip "chalk" used in billiards. Aluminium oxide powder is used in some CD/DVD polishing and scratch-repair kits. Its ...

    en.wikipedia.org/wiki/Passivation_(chemistry)

    In physical chemistry and engineering, passivation is coating a material so that it becomes "passive", that is, less readily affected or corroded by the environment. . Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build by spontaneous oxidation

  5. Glass - Wikipedia

    en.wikipedia.org/wiki/Glass

    Glass-ceramic materials contain both non-crystalline glass and crystalline ceramic phases. They are formed by controlled nucleation and partial crystallisation of a base glass by heat treatment. [87] Crystalline grains are often embedded within a non-crystalline intergranular phase of grain boundaries. Glass-ceramics exhibit advantageous ...

    A single sheet of Glare may be referred to using the naming convention GLARE grade - Aluminum layers / Glass fiber layers - Aluminum layer thickness. The number of aluminum layers is always one more than the number of glass fiber layers, and the aluminum layer thickness is in millimeters, which can range from 0.2 to 0.5 mm (0.0079 to 0.0197 in ...

    The material exhibits a particularly low thermal expansion, with a mean value of 0 ± 0.007×10 −6 K −1 within the temperature range of 0 to 50 °C. [22] High 3D homogeneity [22] with few inclusions, bubbles and internal stria. Hardness similar to that of borosilicate glass. High affinity for coatings. Low helium permeability. Non-porous.

  9. Borosilicate glass - Wikipedia

    en.wikipedia.org/wiki/Borosilicate_glass

    Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
