[001] tilt grain boundaries were studied in bi-crystal samples of melt textured YBa{sub 2}Cu{sub 3}O{sub x}. Grain boundary critical current densities J{sub CB} were obtained from SQUID magnetization measurements on ring samples that contain the grain boundary. The dependence of J{sub CB} on oxygen stoichiometry and oxygen ordering were investigated and preliminary studies of grain boundary doping with selected cations, including Ca, Sr, and Bi were undertaken.
