Abstract

Three phase assemblages were used to produce Bi₂Sr₂CaCu₂O_x (2212) during sintering: a mixture of 20% Ca-rich 2212+80%2212, partially synthesized 2212, and Bi₂Sr₂CuO_x (2201)+(1/2 Ca₂ CuO₃+1/2 CuO) (denoted 0011). The mixture of 2201+0011 produced highly pure 2212 within 50 h of heating in air at ≈850°C. Ag tubes were filled with a mixture of 2201+0011 and worked into tapes by a powder-in-tube process. Heat treatments produced microstructures consisting of small, highly textured 2212 grains. T_c values were ≈70K. Transport J_c values at 4.2K were ≈10⁴ A/cm².
