Comminution - Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earths crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...
Magnetic core - Wikipedia
A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, magnetic recording heads, and magnetic assemblies.It is made of ferromagnetic metal such as iron, or ferrimagnetic …
Allotropes of iron - Wikipedia
Standard pressure allotropes Alpha iron (α-Fe) Below 912 °C (1,674 °F), iron has a body-centered cubic structure and is known as α-iron or ferrite.It is thermodynamically stable and fairly soft metal. α-Fe can be subjected to pressures up to ca. 15 GPa before transforming into a high-pressure form termed ε-iron, which crystallizes in a hexagonal close-packed (hcp) structure.
