1. The areas where crystallite grains meet are known as grain boundaries. 2. This minimizes the overall bond-valence distortions of the crystallite . 3. The crystallite size can be measured directly using transmission electron microscopy. 4. The crystallite size can vary from a few nanometers to several millimeters. 5. These alloys are notable for their toughness, grain boundaries between crystallites . 6. Even a microscopic crystallite is millions of unit cells long. 7. Both polycrystals and crystal powder consist of many crystallites with varying orientation. 8. The term " crystallite boundary " is sometimes, though rarely, used. 9. Crystallites larger than 1 mm and visible to the naked eye can be obtained.10. Metallic materials consist of a microstructure of small crystals called " grains " or crystallites .
