WebCrystalline solids are known as those in which the geometry of the solid is said to be regular. When the Crystalline solids are cut with a knife, a clean surface is obtained. Crystalline solids are also called true solids. Classification of the given compounds as amorphous or crystalline solids: WebA much better descriptive term for this substance would be “microcrystalline graphite” or “cryptocrystalline graphite”. Both of these geological terms are used to describe a mineral which is composed of crystals so small that they cannot be resolved with either the naked eye or through standard optical microscopy techniques.
