Development of Low Iron Loss Soft Magnetic Powder Core

Improving Powder Magnetic Core Properties via Application of Thin, Insulating Silica-Nanosheet Layers on Iron Powder Particles

A thin, insulating layer with high electrical resistivity is vital to achieving high performance of powder magnetic cores. Using layer-by-layer deposition of silica nanosheets or colloidal silica over insulating layers composed of strontium phosphate and boron oxide, we succeeded in fabricating insulating layers with high electrical resistivity on iron powder particles, which were subsequently ...

Soft Magnetic Composites Used for the Iron Core of the Electrical Machines

The electrical machines had a lot of benefits upon the developments made in the last years in the powder material industry. This statement is well proven by the coming out in the last two decades of the transverse flux machines (TFM). The iron core of most of these machines is built of soft magnetic composite (SMC), which allows three-dimensional flux paths. In this paper measurements of a SMC ...

Characterization of Sangan low-grade iron ore and its processing by dry low-intensity magnetic separation

In Sangan iron mine nearly two million tons of low-grade iron ore has been extracted and deposited in the mining site and currently no action is made on them. On the other hand, the mining site is located in the semi-arid region and wet processing has been restricted due to water shortage. In this research, the upgradation of Sangan low-grade iron ore from mine B has been performed by dry low-i...

High Energy Milling of Micro Magnetic Powder for Fingerprint Development High Energy Milling of Micro Magnetic Powder for Fingerprint Development

Highly reflective magnetic powders have been available commercially for latent fingerprint development on dark background surfaces for a few years, however there are needs of a superior darker variety of the magnetic powder which would be ideally suitable for obtaining good contrast on light background surfaces. A novel dark magnetic powder is therefore suggested for the application in latent f...
