Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP [ 2 ] ) in a hexagonal or an orthorhombic, perovskite -like form, and the monoclinic Y 4 Al 2 O 9 (YAM [ 3 ] ).
Uvarovite is a calcium chromium garnet with the formula Ca 3 Cr 2 (SiO 4) 3. This is a rather rare garnet, bright green in color, usually found as small crystals associated with chromite in peridotite, serpentinite, and kimberlites. It is found in crystalline marbles and schists in the Ural Mountains of Russia and Outokumpu, Finland.
Roman numerals: for example the word "six" in the clue might be used to indicate the letters VI; The name of a chemical element may be used to signify its symbol; e.g., W for tungsten; The days of the week; e.g., TH for Thursday; Country codes; e.g., "Switzerland" can indicate the letters CH; ICAO spelling alphabet: where Mike signifies M and ...
Gadolinium gallium garnet (GGG, Gd 3 Ga 5 O 12) is a synthetic crystalline material of the garnet group, with good mechanical, thermal, and optical properties. It is typically colorless. It has a cubic lattice, a density of 7.08 g/cm 3 and its Mohs hardness is variously noted as 6.5 and 7.5.
