METHOD OF MANUFACTURING REPLICA FOR ANALYSIS OF MICROSTRUCTURE OF FROZEN ROCKS IN SCANNING ELECTRON MICROSCOPE

摘要

FIELD: chemistry.;SUBSTANCE: sample surface is obtained by split of a monolith, after which a successive application of polymer solutions on the sample is performed. As the polymer solutions used are: first, a 0.5% solution of formvar in dichloroethane, and then, a 2% solution of polymethylacrylate in dichloroethane with an exposure of the sample at a negative temperature to dry each layer and obtain a solid film. After drying the obtained film with particles of soil is detached from the sample and analysed in a scanning electron microscope.;EFFECT: method improvement.;4 dwg
