Low-Resistance Bi/Pb Ceramics Containing Ts = 295К-315k Phases Synthesized In A Solar Furnace (Parkent), Gulamova Dilbara, Gulamov Timur

CHEMISTRY AND CHEMICAL ENGINEERING

The aim of this work is to obtain bulk textured superconducting ceramics based on glass-crystalline precursors of the Bi1.7Pb0.3Sr2Ca(n-1)CunOy (n=5-9) series. Technologies for obtaining superconducting materials are presented. The advantages of melt methods and “Super Fast Aloys Quenching–T” technology is shown. Compositions, methods of synthesis and study of properties of precursors and ceramics obtained by solar energy are presented. The interrelation of the morphology of glass-crystalline precursors and superconducting ceramics based on them is revealed. It is shown that nano-sized nuclei are the basis on which superconducting phases with Ts = 295-315K are formed as a result of the peritectic …

Bases Of Development Of Technologies Of Synthesis Of Oxide Materials In Big Solar Furnace (Parkent), Gulamova Dilbara, Baxronov Khayot, Bobokhulov Sirojiddin, Eshonkulov Elyor

CHEMISTRY AND CHEMICAL ENGINEERING

The advantages of synthesis of complex oxide compounds by solar energy, the possibility of obtaining highly textured nano materials are shown. The development of heliomaterial science, aimed at the synthesis of new materials, is inextricably linked with the use of effective optical energy systems. On the example of obtaining superconducting materials of nominal composition Bi1.7Pb0.3Sr2Ca(n-1)CunOy (n = 3-20), optimization of the parameters of the optical-energy system of the Big Solar Furnace (Parkent) is shown. The ideology of developing heliotechnology for the synthesis of inorganic materials in a solar furnace is presented. The properties of a superconducting material of nominal Bi1.7Pb0.3Sr2Ca(n1)CunOy …
