The critical current and flux pinning properties of melt grown YBa2Cu3OT\_6 bulk material were investigated by transport measurements and V-I characteristics. A J¢ of 16 000 A cm -2 in zero field and 3000 A cm -2 in 1 T at 77 K was obtained using a criterion of 3.3 I~V cm-~. No features of granulari
