The Iron Production Process: Isostatic Pressing - News ...

Today I will introduce you to the fifth process of magnets. What is it? That is isostatic pressure. The density of the green compact pressed by the field-oriented molding process is about 3.2-3.8g/cm³, and the ideal density of the neodymium iron boron magnet after sintering should be about 7.5g/cm³, so the shrinkage is relatively large when pressing larger cylinders and squares It is easy to ...

Magnetic Iron Oxide Nanoparticles - an overview ...

A facile method to produce magnetic iron oxide nanoparticles is the room temperature co-precipitation (RTCP) of mixed valence iron salts by titration of base in an inert atmosphere. 1,2 This method produces particles around 15 nm in diameter. The size, shape, crystallinity and polydispersity are all dependent on the conditions of the reaction.
