Yuri Leonidovich Belousov (Russian: ?´??? ?????´????? ????´????; November 14, 1945 Chelyabinsk Oblast, USSR — May 4, 2000, Yekaterinburg), Sverdlovsk Oblast, Russia, was a researcher and engineer in the field of Materials Science: glass and Glass-ceramic technologies.
Yuri Belousov authored or co-authored numerous books and publications, and earned more than 10 patents and inventions related to new glass-ceramic materials, colored glasses, foam glass and ceramic glazes with high thermal shock resistance for carbon containing materials.
His main achievements, which were developed in the USSR, include a unique method of glass annealing and toughening (together with O.V.
Mazurin; see toughened glass, annealing (glass)), obtaining the first USSR free-dust method of sealing of glass ampoules which prevented
the ingress of glass dust into medicinal ampouled preparations (in collaboration with O.V.
Mazurin and others).
Yuri Belousov is also the main author and creator of a theoretical method of determining viscosity of silicate melts, allowing one to perform theoretical calculations of viscosity and thus predict commercial glass, cement and slag compositions.
