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 results of the study on the synthesis of high-temperature superconductors in the system Bi-Pb-Sr-Ca-Cu-O based on amorphous precursors were considered in this article, and were obtained under the influence of the radiant flux. A study of the elemental composition of amorphous precursors has showed the presence of 20 at.% superstoichiometric oxygen. The increase in the rate of formation of the superconducting phase and the high texture of the particles in the ceramic samples along the plane [00I] were established. The synthesized samples were composed of superconducting phase Bi 1 , 7 Pb 0 ,3Sr 2 Ca2Cu 3 O y . Research has established a presence in samples of HTSC phase with T c up to 181K.
