Defended her dissertation in 1940 in analytical chemistry at Stockholm. University, and from 1950 was professor of inorganic chemistry at the Royal Institute. In his early career, he mostly worked with X-ray diffraction as. A method of determining mineral phases, especially in the case of bismuth. He then became an internationally known solution chemist.

His publications are considered standard works in geochemistry, and his work. Influenced other well-known geochemists such as Robert Garrels and Werner. Sillén was a pioneer, especially when it came to understanding the. Previously, it was thought that the chemistry. Of seawater was determined by weathering from various minerals.

To show that precipitation reactions were also significant, and his hypothesis. Was that the composition of seawater could be calculated from nine different. Furthermore, Sillén was very active in the compilation. Of thermodynamic data for equilibrium reactions, and in the 1960s was a pioneer.

In using computer calculations to process equilibrium data from various. Sillén was elected in 1964 as a member of both the Academy of Sciences.
