- Аннотация: The crystal growth experiments were carried out by cooling paraffin melt in the temperature range of 55-45oC. The grown crystals were studied by electron and optical microscopies, and also by X-ray diffraction method. It was identified both hexagonal and orthorhombic crystals. Hexagonal and orthorhombic forms of normal paraffins crystallise at the cooling rates of 25.5, 10 and 4oC/h in the above temperature range, and dimensions of the plate-like crystals increase in about 1.5-2 times with decreasing cooling rates. Final crystalline solids contain about 85% of their mass of orthorhombic paraffin crystals. Hexagonal crystals were partly presented by dendrites.
