Determination of the reactivity thermogravimetric method
1 Scope
YS/T of the provisions of section 63 of the method of thermogravimetric (TGA) was measured prebaked anode carbon dioxide reactive.
This section applies to the determination of prebaked anode carbon dioxide reactivity thermogravimetric (TGA). Since the heating conditions, the sample size, material, measured
The mass loss rate and the subsequent reaction of diversity, a lot of available devices. This section provides the sample size, reaction temperature, surface stream
Speed and reaction time, so that the results of different devices measured are comparable.
