Modification of the Hematite Filling Surface of New Composition Material during High Pressure Testing

Abstract:

The paper presents the results of the researches on structure modifications of the surface of iron-ore hematite concentrate under the pressure up to 20000 MPa with the use of modern research method – scanning electron microscopy. Hematite iron-ore concentrate (hematite) is the filling for the newest composite material which can be used in the domain of nuclear building. Such composite material has the same aluminum containing matrix in its base and it contains significant amount of such filling. This modern composite material can be used for engineer structures that can experience high pressure even in extreme cases (fires, sharp dynamic load and strikes). The images of the surface of hematite particles under the pressure of 5000 MPa, 10000 MPa, 15000 MPa and 20000 MPa were studied.
