WEBThe coalifiion of peat to brown coal transforms the degraded plant matter from a hydrosol (an aqueous dispersion containing about 10% solids) to a colloidal gel of about 3040% solids. The water in brown coal is an integral component of the structure and its removal results in the irreversible loss of the gel structure, the formation of a xerogel.
