Title: Manufacture of neutron absorbing pellet, pellet obtained and usage of said pellet
Inventor: JIYAN BUTAN
IPC: G21C7/24
Filed: 1989-09-14
Abstract: PURPOSE: To manufacture a compression pellet with a section a non-circular contour in projecting or partially recessed shape by eliminating a conversion processing that is complex and is expensive since a pure Hf in electrolysis crystal form. CONSTITUTION: A method is related not only to the manufacture of a pellet including Hf in electrolysis crystal form but also to the manufacture of a pellet that includes both Hf and B4 C in a selected ratio. In this case, the ratio of Hf/(Hf+B4 C) should be 0.20-0.80. The neutron absorption capacity and mechanical strength of a compression-molded product can be adjusted by introducing metal elements Zr and Ti that are melted at 400 deg.C or higher into a mixture to be compression-molded when no sintering treatment is performed especially. The pellet is normally formed by repeating filling and compression treatment repeatedly for many times. In that case, sintering treatment should be performed.  The sintering is normally performed at a temperature of normally 1,970-2,030 deg.C under pressure and in reduction atmosphere before performing grinding treatment such as polishing by a polishing whetstone.
