- An amorphous or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal.
- In brief, an amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel.
- Quartz glass (SiO2) is an amorphous solid due to its short range order of constituent particles. Note Quartz is a crystalline solid while quartz glass is an amorphous solid.

Amorphous Solid: Definition
An amorphous solid is a solid material that lacks a definite long-range ordered structure, meaning the molecules or atoms are arranged randomly. They are also known as non-crystalline solids.
Examples of Amorphous Solids
a) Quartz Glass (SiO2): Quartz glass is an amorphous solid that is formed by the rapid cooling of molten quartz. It has a random arrangement of silicon and oxygen atoms, which prevents the formation of a regular crystal lattice.
b) Chrome Alum: Chrome alum is a crystalline solid that has a well-defined structure. Therefore, it is not an example of an amorphous solid.
c) Silicon Carbide (SiC): Silicon carbide is a crystalline solid that has a well-defined structure. Therefore, it is not an example of an amorphous solid.
d) Graphite: Graphite is a crystalline solid that has a well-defined structure. Therefore, it is not an example of an amorphous solid.
Conclusion
Among the given options, only quartz glass (SiO2) is an example of an amorphous solid, while the other options are crystalline solids with well-defined structures.
