Synthesis and processing parameters for (Hg1-xBix)Ba2Ca2Cu 3.1Oy were optimized for growth at temperatures suitable for growth on Ag and Au substrates (<850°C). Use of Bi2CuO4 as a Bi source combined with variations of BaCaCuO precursor phase assemblages allowed the formation of some liquid phase during the reaction and resulted in dense (Hg1-xBix)Ba2Ca2Cu 3.1Oy samples with aligned colonies of grains. Magnetization measurements in fields up to 30 T indicated good intergrain coupling within the large grain colonies. The results of the Bi doped samples are compared with those of previously reported Re doped samples.
