EBSD grain size distribution of the cross section of a gold wire within a silicon matrix from inside a CPU (central processing unit of a computer). The grains are highlighted with arbitrary colors.

High-Quality EBSD Sample Preparation

This article describes a method for EBSD sample preparation of challenging materials. The high-quality samples required for electron backscatter diffraction are prepared with broad ion-beam milling.

Porous Ceramics - Sample Preparation for SEM

Application Note for Leica EM RES102 - Ceramic membrane filters with pore sizes down to a few nanometres must be investigated in cross-section with regard to the structure of the pores. The smallest…

Paper Samples - Sample Preparation for SEM

Application Note for Leica EM RES102 - A coated paper sample has been prepared with ion beam slope cutting in order to test the procedure with regard to its applicability. With the use of ion beam…

Ion Beam Polishing of Sample Surfaces - Sample Preparation for SEM

Application Note for Leica EM RES102 - Ion milling can be used to reduce the roughness of sample surfaces. Small angles less than 6° with respect to the sample surface are necessary. The high voltage…
