Scope

This document specifies the method for determining the mass loss of alumina at 300℃ and 1000℃. The mass loss of the original sample after drying at 300℃ is expressed in terms of moisture content (MOI). The mass loss of the pre-dried sample at 300℃ when it is calcined at 1000℃ is expressed in terms of loss on ignition (LOI).
This document is applicable to the determination of mass loss in alumina. The measurement range of mass loss at 300℃ is 0.20%~5.00%, and the measurement range of mass loss at 1000℃ is 0.10%~2.00%. Instrumental analysis is not an arbitration test method.
