Philtro Amdemrte and Rare Earth Magnets
Quartz Obsession’s podcast episode focuses on the past and importance of rare earth magnets to our modern society. It also gives an overview of rare Earth magnet production in China. China is responsible for 87% of global magnet production. Japan is the other major source, sourcing the majority of rare earth magnets from Australian rare earth giant Lynas. This podcast is available to listen to on iTunes, Stitcher, and Stitcher.
Neodymium-iron-boron magnets
China is a world leader in the production and distribution of rare earth magnets. In contrast to lead and tin which are plentiful in the Earth’s crust rare earths don’t naturally occur in seams. Additionally, the production of rare earth magnets in China is limited by China’s trade restrictions which has prompted research efforts to create powerful magnets without rare earth metals.
Many rare earth and neodymium-based magnets are used in a variety of ways. In one study magnetic oxide nano particles were more easily absorbed into cells. The scientists grew human stem cells in serum-free medium , and added non-toxic magnetic nano particles that contained iron to the medium on a daily basis. The magnets were found to influence stem cell proliferation capacity and prepotency.
Model U Traps
The Model U Trap utilizes a Rare Earth magnetic circuit to separate ferrous and weak magnetic contaminants from your product. The Model U Trap features a clean, 316-stainless steel frame and ACME threads that allow for installation into three or four inch lines. The Model U trap can be equipped with Xtreme elements, which provide greater performance at higher temperatures. It’s used to get rid of magnetic contaminants from a variety of products.
The Model T Traps are designed to reduce the chance of damage to your processing machinery. The trap is constructed with a reinforced tube and plate construction to ensure durability and safety. It can withstand a working pressure of 75 PSI. The traps are usually mounted upright, but can be installed sideways or vertically. They also have a deflector to expose suspended solids that interfere with the flow.
Dura magnets
Rare earth magnets are exceptionally robust and possess high coercivity. Rare earth metals are just as widespread in the Earth’s crust as lead and tin. They aren’t found in the crusts of Earth naturally, and their primary source of supply comes from China. Due to the recent restrictions imposed by China on rare earth magnets companies have been working to create magnets that are strong without the need for them.
Neodymium magnets were invented by General Motors in the 1980s. They are extremely durable and are used in numerous consumer and industrial products. They are also used in jewelry clasps as well as magnetic hold downs. They are the strongest and economical of all rare earth magnets. They can withstand strong forces and are extremely robust. However, their lower cost makes them more prone to oxidation than other magnets like cobalt or samarium. It is important to choose an earth magnet that is rare with careful consideration.
China’s dominance in rare earth magnets
China’s dominance of the production and sale of rare earth magnets is a growing concern for Western companies. These materials are vital for the creation of energy-efficient generators and motors and a deficiency of them could leave companies in uncertainty. In 2011, when China limited its exports of rare earth metals prices shot up. Recent trade wars between China and the United States of America and China have increased the cost of.
The majority of the world’s rare earths market was governed by the United States before China began to enter it. However environmental pressures have led to the shift of production to other countries. Many companies began to source materials from China because of the lower labor costs in China than the U.S. China’s market was overtaken by cheaper Chinese imports of these strong magnets & rare earths.
Safety concerns
The magnet industry has begun to respond to the safety concerns raised by its products which includes the potential health risks associated with rare earth magnets. They are now working on voluntary safety standards designed to strike a fair balance between safety and commercial interests. While CPSC and industry officials claim the new standards will help consumers but they have not consider safety groups or regulatory agencies into consideration. A Washington Post review revealed that industry officials did not address concerns about magnets and other items and that has led to confusion.
Rare earth magnets are flammable. The metal powder they release when they are used can ignite in a flash and is dangerous to children. Rare earth magnets are not suitable for toys, construction toys, and games. They should not be exposed any way to corrosive gases or organic solvents. strong magnets & Rare earth magnets can be damaged by even small impacts or cutting. They also lose magnetic strength or even shatter when they are processed.
Applications
China is intensifying its efforts to keep its lead in the rare earths market, enforcing regulations across the entire industrial chain. China is the primary producer of the majority of rare earth magnets and other metals and a lot of Chinese researchers are concerned that their country is being out-competed by its competitors in more advanced products. This article examines China’s rare Earth magnet manufacturing strategy.
Rare earth magnets are well-known for their strength and long life expectancy. They possess a high magnetic anisotropy. This means that they preferentially attract along the axis of a crystal. These magnets can be made in smaller sizes and hold their magnetic charge better than other materials. However, they are susceptible to demagnification due to heat or physical trauma.
