Effects of electron irradiation on the phase and microstructure of TiO 2 added Bi2Sr2CaCu2O8 (Bi-2212) superconductor ceramics

For high-temperature superconductors to be used in engineering applications, the compounds must be fabricated into composite elements with the required microstructure to provide mechanical strength. Titanium oxide having very high melting point with low heat capacity, is an excellent candidate for r...
