摘要：

Microhardness measurements of different crystallographic faces of various new and modified organic crystals grown by different techniques were performed. Transparent crystals free from any cracks and defects were cut and polished out of various crystallographic faces of crystals grown by solution temperature lowering (Sol) techniques, while test samples were cut parallel (PL) and perpendicular (PR) to the pulling direction, of the crystals grown by Bridgman-Stockbarger (SB) technique. As expected, it was observed that the microhardness of organic crystals is much lower than inorganic crystals, and varied with crystallographic orientation.
