In most cases, surface observation alone cannot provide information concerning the cross sectional structure of granular materials, layered materials, fibrous materials, and powders, etc. Cross-section preparation is carried out with Minitom™ machine by cutting the samples with a Diamond Cut-off Wheel, which is cooled during the cutting process using distilled water with Corrozip™ additive to improve the cutting and cooling qualities. After the specimen size is adjusted to mounting cup size samples are mounted in epoxy resin by vacuum impregnation with CitoVac™ equipment. Finally, materialographic fine grinding and polishing is performed on fully automated Tegramin-20™ system by using different polishing discs and abrasive media.
