For examples, candle waxes are amorphous solids composed of large hydrocarbon molecules. Amorphous comes from the greek, where the prefixais negation, and the word morfo means form, that is, formless. In addition to being used in the kitchen, it has several applications in industrial processes. Differences between amorphous and crystalline solids duration. Crystalline solids have a sharp melting point and start melting when it reaches a particular temperature. Characterized as being very hard with very high melting points and being poor conductors. Most solids, such as metals, salt, and sugar, are made up of tiny crystals. All of these different arrangements typically feature smaller ions filling in the holes and larger ones making up the primary structure. Start studying examples of crystalline solids and amorphous solids. Gels, plastics, various polymers, wax, thin films are also good examples of amorphous solids. These repeating patterns are what differentiates crystalline solids from amorphous solids such as glass, which have a much more disordered atomic structure. Crystalline substances can be described by the types of particles in them and the types of chemical bonding that takes place between the particles.
