The knife ground sample was used in order to facilitate the grinding process in cryogenic or ball mill. Cryogenic grinding was performed in a cryogenic mill (Spex model 6800, USA) with a self-container liquid nitrogen bath. The pre-cooling time was 5 min and grinding times were in the range from 10 to 50 min (5–25 cycles of 2 min grinding).

The sample holder is now raised and readjusted at marking B, and a fine grinding paper is placed on the working disc instead of the rough grinding paper, whereafter the sample holder is again lowered and urged against the new grinding face at a suitable grinding pressure, which may be lower than that in the rough grinding stage, until the ...
holder until the last polishing step is complete. Once clean, return the specimen holder to the machine for polishing or more grinding in suc-cessive steps on ever-finer abrasives and follow each step with thor-ough cleaning. In many cases, all the grinding can be accomplished in a single step, such as in the procedure described in Table 4.1.
Optimal ergonomics for efficient sample preparation. The HT 350 guarantees safe and perfect surface grinding.
