The price of aluminum dropped thousands of times. Firstly, it was due to the availability of cheap electricity after Siemens improved the generator in the 1870s; secondly, it was because Heroult of France and C.M. Hall of the United States in 1886 respectively developed the electrolysis method of dissolving aluminum oxide in cryolite (Na3AlF6). method. They were both 22 years old at the time. This pioneering work enabled large-scale production of aluminum and established the industrial method of electrolytic aluminum in the world today. So far, various aluminum products have been widely used in thousands of households.
On October 27, 2017, the World Health Organization's International Agency for Research on Cancer released a preliminary list of carcinogens for reference, and aluminum products were included in the list of Class I carcinogens.
On July 30, 2018, an international research team said that they had clearly detected a radioactive molecule (aluminum fluoride, containing the radioactive isotope of aluminum "aluminum-26") in the universe for the first time, and that this molecule may be caused by two Stars collide and "splash" into interstellar space.
