Friedrich Liebau

from Wikipedia, the free encyclopedia

Friedrich Karl Franz Liebau (born May 31, 1926 in Berlin ; † March 11, 2011 in Kiel ) was a German chemist and professor of mineralogy and crystallography at the Christian Albrechts University in Kiel .

Life

Friedrich Liebau grew up as the son of the master upholsterer Otto Liebau and his wife Anna Liebau, nee. Hecklau, with 2 sisters in Berlin. After graduating from high school , he was called up for military service and served in the war from 1944 to 1945. He experienced the end of the war with gunshot wounds in the hospital and thus avoided a long prisoner-of-war imprisonment in Siberia.

After the war he studied chemistry at the Humboldt University in Berlin and later at the German Academy of Sciences in Berlin. Under Erich Thilo he received his diploma in 1951 with the thesis “About Na 2 BeF 4 and its relationship to Ca 2 SiO 4 ” and received his doctorate in 1956 with the thesis “About the crystal structures of (NaAsO 3 ) x , the high temperature modification of Maddrell's salt (NaPO 3 ) x (l), the β-wollastonite CaSiO 3 and some structurally related hydrous calcium silicates. "

In 1952 he married Waltrude Liebau, b. Martini, with whom he had four children: Elisabeth Liebau (* 1953), Martin Liebau (* 1954), Barbara Liebau-Danker (* 1956) and Christine Riewerts (* 1961). In 1960 he fled from East Berlin to the Federal Republic of Germany. Here he went to the Max Planck Institute for Silicate Research in Würzburg as a research associate and completed his habilitation in 1964 at the University of Würzburg with work on the crystal chemistry of silicates .

In 1965 Friedrich Liebau became professor for mineralogy and crystallography at the Christian-Albrechts-Universität zu Kiel . There he continued to research the crystal structure of silicates and derived a classification scheme for it. His book "Structural Chemistry of Silicates", published about this in 1985, is now the generally accepted textbook on the chemical structure of silicates, which make up most of the rocks on earth. 1973–1974 he was Dean of the Faculty of Mathematics and Natural Sciences.

In the 1980s he was concerned with the construction and synthesis of clathrasils , silicate structures with cavities in which organic or inorganic molecules are embedded, and zeolites , aluminum silicate structures with cavities in which cations are embedded. The latter are used industrially in large quantities e.g. B. as an ion exchanger for water softening .

In 1991 he retired and continued to be active in research. Until his death in March 2011 he worked on an extension of the bond valence theory, with which certain material properties e.g. B. the high temperature superconductivity can be described.

Liebauit , a mineral discovered in the Eifel in 1992, is named after him .

Foundation to promote the interdisciplinary nature of crystallography

The Waltrude and Friedrich Liebau Foundation for the Promotion of the Interdisciplinarity of Crystallography is intended to promote the interdisciplinary connection of crystallography with other sciences in teaching and research and to make this connection visible to the public. For this purpose, the foundation awards the Waltrude and Friedrich Liebau Prize to promote the interdisciplinarity of crystallography . This is awarded on behalf of the German Society for Crystallography .
