Crystalline density

WebThe concept of crystallinity has been established based on this two-phase model assumption. There are many experimental methods to determine crystallinity. In … WebCrystalline density can be calculated from the dimensions of the unit cell in the crystal lattice, as determined by X-ray analysis. The amorphous density is measured with solid samples which have been produced by rapid quenching from melt temperatures, so that there is no experimental evidence of crystallinity. What does amorphous mean in glass?
