Replace rare earth metals and other technologies will be a step backwards

Recently, a senior expert Jack Lifton rare published an article entitled " replace rare earth metals and other technologies whether it is a step backwards ? " The article, he pointed out in the article : in 2011 , with the rise in rare earth prices, he would have thought Some car brand manufacturers no longer use rare earth, but now he said he could be wrong , because the application of rare earth permanent magnets in the automotive industry not only make the car weight reduction , but also improve the car's efficiency , therefore , entirely they will be replaced on the resulting technical engineering backwards .

Now, some in the media constantly reports of some large research laboratories replaced , seems to be a prelude to eventually replace rare , but in fact it is unscientific , just like the seventies , people send their platinum, palladium and rhodium have a good catalytic effect , but because of less content and want to replace them as platinum , palladium, rhodium then replace the urgency is even larger than it is now replaced by rare , but the fact is that until now , people still use platinum, palladium, rhodium catalytic .

Like Samsung this technology -intensive high-tech companies , and technology requires a lot of rare earth metals, rare earth resources in South Korea is no country in the past three years, the Government has been a national effort to help collect and store Samsung rare earth resources and technical metal resources for the construction of a complete metal supply chain , rare performance in terms of light is electromagnetic these high-tech -intensive companies such as Samsung must use their reason , rare earth miniaturization can make high-tech products , while the electronic signal into animation, music and images are hard to replace , but if not massive reserves of rare earth resources , Samsung will be difficult to maintain a long-term stay as a high-tech intensive technical leadership .

Finally, the author says : "The world history of science will never be regressive type development : those countries and does not encourage production, metal smelting and manufacturing technology for long-term investments will be difficult to maintain long-term production of high-tech manufacturer in the mouth . time is pressing .
