摘要：
The grain size dependence of the intergrain critical current density J(c)(inter) in untextured YBa(2)Cu(3)Ox ceramics determined both in low and high fields was investigated. Whereas in low fields J(c)(inter) decreases with the mean grain size phi (g), it is one order of magnitude higher and increases with phi (g) in high fields.
