The main difference between crystalline solids and amorphous solids is that crystalline substances have characteristic geometry while amorphous solids do not. In other words, crystalline solids have a definite and orderly shape and amorphous solids do not.Know More
While crystalline solids have a sharp melting point, amorphous solids are softened and melted over an unspecific range of temperatures. For example, glass is gradually softened and melted without undergoing an abrupt change to the liquid state. During the process of crystallization, amorphous solids experience a smooth cooling curve with a continuous drop in temperature. When crystalline substances undergo the crystallization process, they experience two breaks in their cooling curve. The two breaks indicate a period of a constant temperature instead of a continuous decrease in temperature.
The structure of a crystalline solid is much more rigid than the structure of an amorphous solid. Amorphous solids are irregularly broken while crystalline solids cleave along definite planes.
Another difference between these two types of solids is crystalline solids are anisotrophic and amorphous solids are isotrophic. Isotrophic means the solid's properties are independent of the direction in which they are being measured. Anisotrophic means the solid's properties are in different directions. Cellophane is an example of an amorphous solid. Copper is a common crystalline solid.Learn More
Garnets, gold and graphite are all examples of crystalline solids. These items are all defined as crystalline solids by a similar molecular structure characterized by a well-defined, regular arrangement of identical unit cells.Full Answer >

The main difference between a heterogeneous mixture and a homogeneous mixture is the degree to which the materials are mixed together. Generally speaking, a heterogeneous mixture is less well integrated than a homogenous mixture.Full Answer >
Crystalline solids consist of atoms, ions and molecules arranged in definite and repeating three-dimensional patterns. Unlike amorphous solids that melt at a range of temperatures, crystalline solids have definite melting points. Crystalline solids include metallic, ionic, network atomic and molecular solids, and true solids are crystalline.Full Answer >
