from Wikipedia, the free encyclopedia

Yevgeny Alexandrovich Porai-Koschiz ( Russian Евгений Александрович Порай-Кошиц ; born September 15, jul. / 28. September  1907 greg. In the Russian Empire ; †  18th March 1999 in St. Petersburg ) was a Russian solid-state chemist and university lecturer .

Life

Evgeni Porai-Koschiz, son of the chemist Alexander Evgenjewitsch Porai-Koschiz and his wife Tatiana Ivanovna born. Umnowa, studied chemistry at Leningrad University, as did his brother Boris (1909–1968), while his brother Mikhail became a crystallographer .

After completing his studies, Porai-Koschiz worked in the Leningrad State Optics Institute (GOI) with Alexander Lebedew in his candidate dissertation from the states of glass formation ( X-ray examinations ) so that he experienced the first months of the Leningrad blockade . He then defended his dissertation in 1943 in Kazan , where the Leningrad Institute of Technology and the Academy of Sciences of the USSR (AN-SSSR) had been evacuated .

In 1953, Porai-Koschiz successfully defended his doctoral thesis on structural studies of glasses using X-ray methods . He held lectures, became a professor and headed the X-ray laboratory of the Chair of Solid State Electronics at Leningrad University. He examined chemically the structural inhomogeneities in sodium - borosilicate glasses . These investigations were crucial in the manufacture of glass-ceramics , which were important in the development of an optical navigation system for submarines. For this he and the other project participants received the Lenin Prize in 1963 . In the following years, the phase separation in glasses was intensively investigated in the laboratory he led , so that Porai-Koschiz became an internationally recognized expert in this field.

With others, Porai-Koschiz initiated the Russian journal Physics and Chemistry of Glass, founded in 1975 by the AN-SSSR (now the Russian Academy of Sciences (RAN) ) and the Grebenschtschikow Institute for Silicate Chemistry . In 1988 he received the Mott Award and in 1992 an honorary membership of the American Ceramic Society. In 1991 he received the Grebenchtschikow Prize for his work on the structural inhomogeneity of inorganic glasses.
