Reasons for high activity of reduced iron powder
1. Influence of pulverizing process on activity
The pulverizing process plays an important role in the crystalline structure of powder particles.Generally speaking, powder particles have a polycrystalline structure, and the size of the grain depends on the process characteristics and conditions, for very fine powder may appear single crystal particles.The complexity of the actual structure of the powder particles is also manifested by the serious imperfection of the crystal, that is, there are many crystal defects, such as voids, distortions, inclusions and so on.Therefore, powders are always stored with higher lattice distortion energy and higher activity.
2, The influence of the surface state of powder particles on the activity
The surface state of reduced iron powder particles is very complex. The finer the powder particles are, the more developed the outer surface is.At the same time, the defects of powder particles, the inner surface is quite large powder developed surface storage of high surface energy, so the ultrafine powder is easy to spontaneously gather into secondary particles, and easy to oxidize and spontaneous combustion in the air.
