About his discovery, the scientists said at the American geophysical Union held in December 2016 in San Francisco, briefly about it, reports BBC News.
“We believe that silicon is one of the key elements, about five percent of [the inner core of the Earth] by weight may consist of silicon, which is soluble in Nickel-iron alloys,” said lead author of the research Eiji Otani from the University of Tokyo.
their findings, scientists have modeled in the laboratory conditions of the Earth. Them at high pressures and temperatures is the hard core radius of 1.2 thousand kilometers, which earlier was known, it consists 85 percent iron and 10 percent Nickel.
the Work of scientists helped to determine the chemical nature of the remaining five percent. Criticism of scientists say that there is an alternative hypothesis, according to which the Earth’s core besides iron and Nickel, there is not silicon, and oxygen, according to Tape.ru.
