Is Magnetite Magnetic? (Answered)
The sub-conchoidal fracture of magnetite is characterized by its unevenly rounded corners and smooth surface. A splitting or break along structural planes could be visible. However, a concentric ripple-like fracture can happen without following natural separation planes. Magnetite is a crystal with an isometric crystal form. Uses of Magnetite

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 past, it has been called ferrous–ferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary rocks.

3.5.2: Cleavage, Fracture, and Parting
No headers. Cleavage, fracture, and parting are three related terms that describe how a mineral crystal may break. The orientation and manner of breaking provide important clues about crystal structure and can be keys to mineral identification. If breaking produces planar and smooth surfaces, oriented in a particular way relative to a crystal's atomic arrangement, we …
