rupture de magnétite.

Magnetite

Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron (II) and iron (III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron (II,III) oxide. In the …

The dissolution rate constant of magnetite in water at …

In most cases, however, dissolution rate constants for magnetite are not available. At UNB Nuclear we have a research program using a high-temperature loop …

Magnetism of Al‐substituted magnetite reduced …

In order to characterize the magnetic properties of Al-magnetite, two series of Al-magnetite samples were synthesized through reduction of Al-hematite by a mixed gas (80% CO 2 and 20% CO) at …

Rupture Force of Magnetite Chain in a Uniform Magnetic Field

The rupture forces of breaking down a magnetite chain in a uniform magnetic field were measured by using a water flow under microscope observation with …

Geochemistry, Geophysics, Geosystems

On cooling, these hot fluids altered pyrrhotite into pyrite and magnetite into partially altered magnetite. Our results demonstrate that characterization of magnetic minerals provides a useful means of …

Rupture Force of Magnetite Chain in a Uniform Magnetic Field

The rupture forces of breaking down a magnetite chain in a uniform magnetic field were measured by using a water flow under microscope observation with a video camera. The experimental results have...

Basics of Ferrites: Types and Structures | SpringerLink

This chapter summarizes the detailed introduction, types of magnetism, classifications of ferrites and their crystal structure. In addition, this chapter has the main …

Magnetic and electronic properties of magnetite across the …

Here we study the magnetic and electronic properties of magnetite across high pressure anomaly and in the pressure-induced phase by means of 57Fe …

Magnetite Nucleation and Growth | SpringerLink

In this chapter, we will discuss magnetite and its occurrence, its properties in general and of magnetite nanoparticles in particular, and how magnetite can be …

Magnetite : Properties, Occurrence, Formation, Deposits

Magnetite has the chemical formula Fe3O4, which means it is composed of two iron (Fe) ions combined with three oxygen (O) ions. Here is some information on the …
