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 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
An amorphous metal (also known as metallic glass, glassy metal, or shiny metal) is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms .
To this day alclad materials are used commonly in the aircraft industry. [31] [32] The alloys are processed by rolling, forging, extrusion and partly by casting. [33] Typical uses for wrought Al-Cu alloys include: [34] 2011: Wire, rod, and bar for automatic lathe products. Applications where good machinability and good strength are required.
A glass building facade. Glass is an amorphous (non-crystalline) solid.Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics.
Particles of refractory material in contact with aluminium can detach and become inclusions. We can find graphite inclusions (C), alumina inclusions (alpha-Al 2 O 3), CaO, SiO 2, … After some time, graphite refractory in contact with aluminium will react to create aluminum carbides (harder and more detrimental inclusions).

In the case of the AlSiCu alloys, higher proportions of copper are also added, which means that the materials can be hardened (see Aluminum-copper alloy). Together with silicon, magnesium forms the Mg 2 Si (magnesium silicide) phase, which is the basis of hardenability, similar to aluminum-magnesium-silicon alloys (AlMgSi).
