microscopy shows the fine layered – type structure of the grains (Figure 5) which is similar to
the fine structure of the CaF2 natural optical ceramics (Figure 2).
Figure 2. Images of the chip of the cryptocrystalline fluorite sample got by atomic force microscopy
(AFM) (a) and fine structure of the grains at the chemical dropped surface of the chip (b). Shoot is in
the contact mode got at the atomic force microscope Solver P47 (NT – MDT, Moscow).
