The ash hemisphere temperature is an important property of
ash melting behaviour . It is defined as the temperature at which the ash test piece forms a hemisphere (i.e. the height becomes equal to half the base diameter).
This property is determined in a
reducing atmosphere using a carbon
monoxide/carbon dioxide gas mix or a hydrogen and carbon dioxide gas mix. This characteristic temperature can also be
determined in an
oxidising atmosphere , using air or carbon dioxide, using analysis package
P41 - Ash Melting Behaviour (Oxidising Conditions) .
