Павел Степанович Кислый 

1933 – 2019

National Academy of Sciences of Ukraine, Kiev, Ukraine


Professor Pavel S. Kislyi was born on March 5, 1933 in the village Mala Oleksandrivka, Boryspil district, Kyiv region. In 1957 he graduated from Kyiv Polytechnic Institute (now National Technical University of Ukraine Igor Sikorsky Kyiv Polytechnic Institute) by the specialty "Metallurgy, equipment and technology of heat treatment of metals". After KPI he began working for the Frantsevich Institute for Problems of Materials Science of the National Academy of Sciences of Ukraine as an engineer, junior researcher, senior researcher, head of department. He was one of the most talented PhD students and scientists of the Professor Grigory Samsonov’s team. He was focused on the development of the ceramic jet molding for the high melting point compounds, which made it possible to obtain relatively long size thermocouple covers, ceramic pipes and rods using specifically designed and developed molds.

An important area of Dr. Kislyj’s activity was the study of sintering as a process, in particular its kinetics and the ultrasonically activated sintering, which allowed suggesting the role of grain boundary sliding as a rapid rate densification mechanism, especially for nanosize powders.

In 1960th, Dr. Kislyj has developed various high melting point materials and products for applications in special equipment, in particular: protective covers for thermocouples operating at high temperatures of cryolite-alumina melt under oxidizing gaseous media conditions, protective covers for continuous temperature control of the molten steel in open hearth furnace and electric arc furnace, ceramic boats for aluminum evaporation in vacuum, parts for gas turbine engines and propulsion systems.

Industrial production of ceramic parts was organized by Dr. P.S. Kislyj at the Brovary Powder Metallurgy Plant and production of high-temperature heating elements made from molybdenum disilicide has been launched on Kirovakan plant (now Armenia).

Since 1977 till 1990, Dr. Pavlo Kyslyj was at the position of Deputy Director in the Bakul Institute of Superhard Materials of the National Academy of Sciences of Ukraine and headed the department of “High melting point superhard materials”.  Under his leadership the Institute has developed ceramic cutting tool inserts for processing of steel; metal and non-metal dies for wire drawing; nozzles for spraying of pulps and sand in sandblasting machines; parts for shut-off valves in oil wells; thermally conductive electrically insulating substrates for integrated semiconductor circuits; cellular structures for catalyst carriers used in chemical industry and afterburning of automobile engines; armor ceramic plates for military equipment and body protection.

In 1977, Dr. Kislyj was elected a member of the International PlanSee Society of Powder Metallurgy, in 1979 a member of the International Institute of Science of Sintering, and in 1982 a Full member of the International Academy of Ceramics and a Corresponding Member of the National academy of Sciences of Ukraine. He was also a chairman of the section "Refractory compounds" of the USSR State Committee for Science and Technology (1977-1980), a member expert council of the Supreme Attestation Commission of the USSR (1980-1985), editor-in-chief of Ceramic International (1985-1990). In 1992, Dr. Kislyj was elected a Full member of the National academy of Sciences of Ukraine.

His carrier changed with Ukrainian Independency in 1991. He was elected a member of Verhovna Rada (Parlament of Ukraine) and was a Chairman of the Committee on Public Education and Science (1992-1994).He was an adviser for three doctors of sciences and supervisor for 39 PhDs. He wrote of more than 300 scientific papers, including 14 books; has protected his intellectual property with 175 copyright certificates and patents. Dr. Kislyj was awarded with the Order “Ivan Mazepa Cross” (2009); Order of Merit of IIIrd degree (2001), Prize winner of the Council of Ministers of the USSR (1989); the P.G. Sobolevsky Prize (1977); Honored Scientist of Ukraine (1993).

PAVLO S. KISLYJ, the outstanding, very practical ceramic scientist and patriot of Ukrainian Independency died in Kyiv, Ukraine, on December, 2, 2019.
