WebThe Rietveld refinement of the XRD patterns and the Mossbauer spectroscopy confirmed that Y 3+ ions occupy the dodecahedral site, whereas Al 3+ and Fe 3+ ions are distributed in the tetrahedral and octahedral sites of the bcc ( Ia 3 d ) structure of the garnet phase. The Al 3+ ions have a preference to occupy the octahedral site. WebIron has two different crystal structures at atmospheric pressure: the body centered cubic (bcc) and the face centered cubic (fcc). In the ground state the bcc α-phase is stable, and …
WebIn a bcc arrangement, a unit cell contains (8 corner atoms × ⅛) + (1 center atom × 1) = 2 atoms. The packing is more efficient (68%) than simple cubic and the structure is a common one for alkali metals and early transition metals. The primary phase of low-carbon or mild steel and most cast irons at room temperature is ferromagnetic α-Fe.
