Vietnam hopes to strengthen research cooperation in rare earth resources / Vietnam rare earth resources In early June, Vietnam Media issued an article introducing Reuters' interview with Vietnamese Prime Minister Nguyen N. Chung on rare earth mining and renewable energy. Qi Chunfu said that Vietnam hopes to strengthen research cooperation in rare earth mineral resources, promote [...]
The Brief Introduction about Magnetic Boiler Filter The central heating system is a relatively energy-efficient way to heat all of rooms in home. The central heating system of China quite different from other Western countries, and only the people north of the Qinling Mountain-Huaihe River Line can enjoy the central heating, so this line is [...]
The Effect of Environmental Protection Inspection on Magnet Industry The Environment Protection Inspection Team sat off the nationwide environmental storm since last year. Unlike the previous environment renovation, the emphasis and intensity of Environment Protection Inspection is unprecedented this time. For magnet industry, the supply of rare earth element is also affected and eventually it [...]
40 Years Later No Fe16N2 Magnet – Why? • Difficult to synthesize pure Fe16N2 by conventional methods e.g. solubility of N in liquid Fe very low (0.045 versus 5.5 wt % for C). • Alloy cannot be formed by conventional processing methods e.g. melting and casting. • Contradictory results over the years probably due to inconsistent sample preparation and measurement techniques. • Fe16N2 decomposes above 300 C. Fe16N2 Magnet • Cannot be formed by powder metallurgical processing. • Lots of magnetization available but need coercivity for a useful PM compound; theoretical magnetocrystalline anisotropy H is 16 kOe but will need help from other mechanisms e.g. shape, strain. Bulk Fe16N2 Magnet Reported by UMN Team and Niron Magnetics Formed • Strained wire method used to enhance magnetic property; strain‐assisted annealing. Niron Magnetics – Good News • The company is producing bulk iron nitride magnets today for further research and development. • First principles calculations demonstrate a theoretical BHmax of 135 MGOe and Hc of 16 KOe. • Raw materials are cheap and abundant. • Isotropic bonded magnet BHmax > 30 MGOe feasible. Niron Magnetics – Bad News • Iron nitride by itself is inherently heat sensitive. • It decomposes before it sinters – iron nitride magnets will all be bonded in some fashion. • Coercivity needs to be improved. • They will need the same corrosion protection as raw iron. • Niron hasn’t announced a commercial product yet NdFeB Segment Magnets [...]
Your permanent magnet should lose no more than 1% of its magnetic strength over a period of 100 years provided it is specified and cared for properly. There are a few things that may cause your magnet to lose its strength: HEAT Heat above the maximum level rated for the magnet material in your separator [...]
Magnetic Fields What is a magnetic field? A magnetic field is quite simply the area around a magnet in which its magnetism can affect other objects. If you were to be able to see a magnetic field, you would see lines called lines of flux that show the direction of a magnet’s force or field. [...]
Magnetic Circuitry is simply how the magnet is designed to attract and retain ferrous contaminants. MPCO utilizes 3 magnetic circuits; Type A, Type B, and Type C. Type A Circuitry Type A circuits can be used in applications where the highest level of product purity is required. The circuit utilizes a tube, or a series [...]
Radical new maglev elevators that travel in ANY direction could lead to super skyscrapers far taller than today's buildings Technological innovations have allowed us to build skyscrapers to great heights But people still don't live in skyscrapers the way futurists had envisioned This is because elevators are only able to go up and down, and [...]
What Is Magnetotactic Bacteria? In 1963, at the University of Pavia in Lombardy, Italy, Salvatore Bellini was observing bog sediments under his microscope. As opposed to the normal movement, Bellini noticed a group of bacteria orienting themselves in a unique direction. Upon further study, he realized that these peculiar microorganisms were moving in the direction [...]
