Crystallites are a part of?

Explanation

Amorphous solids do not have a regular, ordered arrangement of atoms or molecules. This disordered arrangement gives amorphous solids their characteristic properties, such as their softness, their low melting point, and their inability to reflect light.Crystallites are a type of amorphous solid. They are small, randomly oriented regions of order that form in amorphous solids. Crystallites are typically very small, on the order of nanometers. They are also very disordered, with the atoms or molecules in the crystallites being arranged in a random order.The presence of crystallites in amorphous solids gives them some of the properties of crystalline solids. For example, amorphous solids with a high concentration of crystallites can be hard and have a high melting point. However, amorphous solids with a low concentration of crystallites will be soft and have a low melting point.
