The primitive cell contains two formula units of aluminium oxide. Aluminium oxide also exists in other metastable phases, including the cubic γ and η phases, the monoclinic θ phase, the hexagonal χ phase, the orthorhombic κ phase and the δ phase that can be tetragonal or orthorhombic. [16] [17] Each has a unique crystal structure and ...
Corundum. Corundum is a crystalline form of aluminium oxide (Al2O3) typically containing traces of iron, titanium, vanadium, and chromium. [3][4] It is a rock -forming mineral. It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [7]
Sapphire is one of the two gem-varieties of corundum, the other being ruby (defined as corundum in a shade of red). Although blue is the best-known sapphire color, it occurs in other colors, including gray and black, and also can be colorless. A pinkish orange variety of sapphire is called padparadscha.
Aluminium oxides or aluminum oxides are a group of inorganic compounds with formulas including aluminium (Al) and oxygen (O). Aluminium (I) oxide (Al2O) Aluminium (II) oxide (AlO) (aluminium monoxide) Aluminium (III) oxide (aluminium oxide), (Al2O3), the most common form of aluminium oxide, occurring on the surface of aluminium and also in ...
Aluminum oxide crystals. Germanium: This was the material in the first transistor invented by Bardeen, Brattain, and Shockley in 1947. It is used in some gamma-ray detectors and infrared optics. [27] Now it has become the focus of ultrafast electronic devices for its intrinsic carrier mobility. [26]
Infobox references. Aluminum silicate (or aluminium silicate) is a name commonly applied to chemical compounds which are derived from aluminium oxide, Al 2 O 3 and silicon dioxide, SiO 2 which may be anhydrous or hydrated, naturally occurring as minerals or synthetic. Their chemical formulae are often expressed as xAl 2 O 3 ·ySiO 2 ·zH 2 O.
Zeolite is a family of several microporous, crystalline aluminosilicate materials commonly used as commercial adsorbents and catalysts. [1] They mainly consist of silicon, aluminium, oxygen, and have the general formula Mn+. 1/n(AlO. 2)−. (SiO. 2) x ･y H. 2O where Mn+. 1/n is either a metal ion or H +.
Calcium aluminates. Crystal structure of dodecacalcium hepta-aluminate, 12CaO·7Al 2 O 3 (C12A7). [1] Calcium aluminates are a range of materials [2] obtained by heating calcium oxide and aluminium oxide together at high temperatures. They are encountered in the manufacture of refractories and cements. The stable phases shown in the phase ...
