    Ash Hemisphere Temperature (Reducing)

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).
