Week 9/19 Free Post: Material Science Excitement
Hello everyone, for this weeks free post I am going to be talking about a news story I found about material science that I found interesting. I mostly found it interesting because I found it quite astounding that material scientists could be involved in a process like this. The article discusses a new technique that could be used to extract magnesium from the depths of the ocean.
This magnesium can be used to to make more fuel efficient cars and planes, more stable buildings, and more efficient power generation systems since it is much more lightweight than the traditional steel used currently. The downside is right now it takes 7 times the energy to pull magnesium from the earth as it takes to extract steel. The most energy efficient method is used in Utah, which is done by pulling it out of molten salt. This process still requires temperatures of 900 degrees Celsius, which requires a lot of energy. China uses a different method, which requires significantly more energy and gives off even more carbon emissions.
With the new method, the temperature required will be no more than 300 degrees Celsius and will give off far less carbon emissions. This process will greatly decrease the American dependency on foreign importers of magnesium, and will significantly increase the American magnesium market. This is approximated to be 50% more efficient than the current process used in Utah.
I found this article quite interesting. It is inside my range of interests and I will be looking for more updates on it when there is more information available. I am curious to see if the scientists will be able to get this process rolling, and to see if they will release more information on how they did it. Thank you very much for reading!
