Description

In a huge number of works on the synthesis of high-temperature superconductors (HTSCs), two main directions are distinguished: works on the synthesis of new superconductors ([1] -as well as references therein), and works on the development of new methods for improving the physical parameters of traditional HTSC materials [2–4].

In this paper, we consider three methods for the synthesis of HTSC ceramic samples under the influence of external acoustic waves:

a) Shock-wave compression of a powder mixture before synthesis.

b) Creation of acoustic waves on the surface of the HTSC sample during sintering in a furnace. The idea was proposed by a member. corr. NAS of Armenia, Academician A.R. Mkrtchyan.

g) The use of dopant powdered HTSC impurities before
