Product Details
ISO 806:2004 specifies a method for the determination of loss of mass on heating of aluminium oxide at 300 °C and further loss of mass on ignition at 1 000 °C. By industry convention, these mass losses are often referred to as moisture (MOI) and loss on ignition (LOI) respectively.
This method is suitable for calcined alumina in the range 0,2 % to 5 % loss of mass at 300 °C and 0,1 % to 2 % loss of mass at 1 000 °C.
This method provides for samples to be treated on an as-received basis for determination of actual MOI and LOI in alumina samples. To improve precision of analysis in cases where as-received results are not required, samples can be air-equilibrated prior to analysis. Air-equilibration can greatly affect MOI results and significantly alter LOI results. The air-equilibration procedure and its effects are discussed.
Instrumental methods are also discussed.
