Determination of Free α-SiO2 Content in Mill Scale by X-ray Diffraction K Value Method
Yankuang ceshi, 2015 At present, free α-SiO2 content is often determined by the pyrophosphate method and X-ray Diffraction (XRD) method. However, insoluble materials including FeO, Fe3O4 and Fe2O3 in mill scale cannot be decomposed by pyrophosphate, and thus the ...
