Crystal orientation regulation in ostrich eggshells
01/12/2001 · Fig. 2 is the XRD patterns of the powder specimens of the cone layer, palisade layer and crystal layer of the ostrich eggshell. It is confirmed that the inorganic phase in the three layers is calcite. It can also be seen that in the three layers, the (1 0 4) crystalline plane has the strongest diffraction intensity.
