The loss on ignition is reported as part of an elemental or oxide analysis of a mineral. The volatile materials lost usually consist of "combined water" ( Hydrate s and labile hydroxy-compounds) and Carbon Dioxide from carbonates. It may be used as a quality test. For example, the loss on ignition of a Fly Ash consists of contaminant unburnt fuel. In Pyroprocessing industries such as Lime , calcined Bauxite , Refractories or Cement manufacture, the loss on ignition of the raw material is roughly equivalent to the loss in mass that it will undergo in a Kiln . The loss on ignition of the product indicates the extent to which the pyroprocessing was incomplete. REFERENCES |
