ABSTRACT
Composition: Al
Molar mass: 26.9815
Density (g cm
K3
): 2.69
The space lattice of Al belongs to the cubic system, and its face centered cubic lattice has a lattice
constant of aZ0.404145 nm (258C).
Al is contained within feldspar, mica, cryolite, clay, bauxite, spinel, etc., and typically manufac-
tured by the electrolysis method using cryolite and alumina as raw materials. Fe, Si, P, Ca, Mg, etc.,
are included as impurities. The crystal pulling from melt and the zone melting method are utilized
to grow single crystals.
