AMORPHOUS  SOLIDS OR NON-CRYSTAL SOLIDS

See Crystal solid or substances

Amorphous solids are Non-Crystal solids

They have opposite properties to crystal solids

Examples of Amorphous substances are glass and plastic.

Substances that form amorphous solids are generally made up of long chain-like molecules that are intertwined in the liquid states mostly in long chain hydrocarbon.

Amorphous solids are not real solid but super cooled liquid because their molecules are in disarrayed form and in non-specific   pattern.  When the temperature is increased they become soft , hence their crystallization can never  occur. They only solidified because of lower temperature.

 

General Characteristic of Amorphous Substances

The general characteristic of Amorphous substances are opposite of those of crystal substances

  1. No definite melting point.
  2. No definite shapes.
  3. They do not form crystal , hence crystallization cannot be achieved .
  4. They are usually insoluble
  5. They are mostly anhydrous.
  6. They become soft when heated and easily melted without definite melting point.
  7. They have weak force of attractions within the molecules.
