An example of a five-numbered formation would be 4–1–2–1–2, where the midfield consists of a defensive midfielder, two central midfielders and an offensive midfielder; this is sometimes considered to be a kind of 4–4–2 (specifically a 4–4–2 diamond, referring to the lozenge shape formed by the four midfielders).
One unit cell, 3. A lattice of 3 × 3 × 3 unit cells. Diamond's cubic structure is in the Fd 3 m space group (space group 227), which follows the face-centered cubic Bravais lattice. The lattice describes the repeat pattern; for diamond cubic crystals this lattice is "decorated" with a motif of two tetrahedrally bonded atoms in each primitive ...

In the early development of the game, formations were much more offensively aggressive, with the 1–2–7 being prominent in the late 1800s. [1] In the latter part of the 19th century, the 2–3–5 formation became widely used and the position names became more refined to reflect this. In defence, there were full-backs, known as the left-back ...
An example of the use of this is the FC Barcelona team, who use a fluid (meaning the players are free to move around and exchange positions) 4–3–3 formation to use the channels created by the oppositions formation to gain an advantage, e.g. Xavi with the ball in midfield, passing to one of the front three players who start either in the ...
This also called '3:2 mullite' to distinguish it from 2Al 2 O 3 ·SiO 2, Al 4 SiO 8 '2:1 mullite'. 2Al 2 O 3 ·SiO 2, Al 4 SiO 8 '2:1 mullite'. [6] The above list mentions ternary materials (Si-Al-O). Kaolinite is a quaternary material (Si-Al-O-H). Also called aluminium silicate dihydrate, kaolinite occurs naturally as a mineral. Its formula is ...
A silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula [SiO (4-2x)− 4−x] n, where 0 ≤ x < 2. The family includes orthosilicate SiO 4− 4 (x = 0), metasilicate SiO 2− 3 (x = 1), and pyrosilicate Si 2 O 6− 7 (x = 0.5, n = 2). The name is also used for any salt of ...
