ქიმიის ტერმინთა განმარტებითი ლექსიკონი

Notes:

1. The assumption is made that the sample can be subdivided into a crystalline phase and an amorphous phase (the so-called two-phase model).
2. Both phases are assumed to have properties identical with those of their ideal states, with no influence of interfaces.
3. The degree of crystallinity may be expressed either as the mass fraction or as the volume fraction, the two quantities being related by w_c = ϕ_c ñ_c / ñ , where ñ and ñ_c are the densities of the entire sample and of the crystalline fraction, respectively.
4. The degree of crystallinity can be determined by several experimental techniques; among the most commonly used are: (i) X-ray diffraction, (ii) calorimetry, (iii) density measurements, and (iv) infrared spectroscopy (IR).
