  2. 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.

  3. Passivation (chemistry) - Wikipedia

    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

  4. Aluminium oxide - Wikipedia

    en.wikipedia.org/wiki/Aluminium_oxide

    Al 2 O 3 is an electrical insulator but has a relatively high thermal conductivity (30 Wm −1 K −1) [2] for a ceramic material. Aluminium oxide is insoluble in water. In its most commonly occurring crystalline form, called corundum or α-aluminium oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting ...

  5. GLARE - Wikipedia

    en.wikipedia.org/wiki/GLARE

    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 ...

  6. Vitrification - Wikipedia

    en.wikipedia.org/wiki/Vitrification

    The most common applications are in the making of pottery, glass, and some types of food, but there are many others, such as the vitrification of an antifreeze-like liquid in cryopreservation. In a different sense of the word, the embedding of material inside a glassy matrix is also called vitrification. An important application is the ...

  8. Surface grinding - Wikipedia

    en.wikipedia.org/wiki/Surface_grinding

    Factors to consider in surface grinding are the material of the grinding wheel and the material of the piece being worked on. Typical workpiece materials include cast iron and mild steel. These two materials don't tend to clog the grinding wheel while being processed. Other materials are aluminum, stainless steel, brass and some plastics.

  9. Aluminium smelting - Wikipedia

    en.wikipedia.org/wiki/Aluminium_smelting

    Cryolite is a good solvent for alumina with low melting point, satisfactory viscosity, and low vapour pressure. Its density is also lower than that of liquid aluminium (2 vs 2.3 g/cm 3 ), which allows natural separation of the product from the salt at the bottom of the cell.
