Bengt Aurivillius

Bengt Aurivillius (4 December 1918 in Linköping – 2 May 1994 in St. Peter's Parish, Malmöhus County By 1949, he had made some important discoveries about the oxidation of mixed metals, which became quite prominent in the world of chemistry. He completed his dissertation, "X-ray Examinations of Bismuth Oxifluoride and Mixed Oxides with Trivalent Bismuth", at Stockholm University in 1951. Aurivillius joined the Swedish National Defence Research Institute in 1952, where he worked first as a research engineer and later senior researcher. and bismuth layer structured ferroelectrics based on the oxide perovskite structure, which was later named after him as the Aurivillius phases. He characterized the ferroelectric properties of these materials, which have become a family of materials for lead-free ceramics.

Personal life Bengt Aurivillius is a member of the Aurivillius family, his father was the entomologist Christopher Aurivillius. His wife was crystallographer Karin Aurivillius.
