These solids have the ability to flow very slowly due to which they are also termed as pseudo solids or super cooled liquids .
These solids are isotropic in nature due to the absence of long range order and irregular arrangement of the constituent particles in all direction . This leads to same value of physical property along all the direction .

Glass , rubber , amorphous silicon and plastics are typical examples of amorphous solids .
Amorphous silicon is a photovoltaic material widely used for conversion of sunlight into electricity .

This range of solids consists of a broad range of small crystals having a definite characteristic geometrical shape .
