Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The article presents the research results on the synthesis of HTSC ceramics using concentrated radiant radiation. It was established that all synthesized samples of the nominal composition Bi 17 Pb 03 Sr 2 Ca n-1 Cu n O y (n = 3, 4, 5), the main phase was the superconducting phase Bi 17 Pb 03 Sr 2 Ca n-2 Cu n O y , which has a critical temperature of the transition to the superconducting condition of 107 K. Also in samples of nominal compositions Bi 1,7 Pb 0,3 Sr 2 Ca n-1 Cu n O y (n = 4, 5) showed traces of phases with higher T c .
