Carbonaceous materials used in the production of aluminium. Baked anodes and sidewall blocks. Determination of the reactivity to air - Thermogravimetric method Ingestion-build-143074 Steel gate valves1 Scope This part of ISO 12989 allows the determination by thermogravimetric analysis (TGA) of air reactivities and dusting of shaped carbon electrodes used in the aluminium reduction industry. Many types of apparatus are available, with various thermal conditions, sample size capabilities, materials of construction and procedures for determining the mass loss and subsequent rate of reaction. This test method standardizes the variables of sample
