A solid decompostion product of a natural or synthetic organic material.
Note:
If the precursor has not passed through a fluid stage, char will retain the characteristic shape of the precursor (although becoming of smaller size). For such materials the term 'pseudomorphous' has been used. Some simple organic compounds, e.g. sugar, melt at an early stage of @[email protected] and then polymerize during @[email protected] to produce chars.
