This patent describes a method of making burnable neutron-absorber bodies for the burnable-poison assemblies of a nuclear reactor. The process consists of: (a) producing a slurry of a powder of a refractory material including one or more of the class consisting of Al/sub 2/O/sub 3/ and ZrO/sub 2/; (b) adding a binder to the slurry; (c) drying the slurry to produce a powder of agglomerated particles of one or more of the class of Al/sub 2/O/sub 3/ and ZrO/sub 2/ including the binder; (d) mixing the powder with a powder of the class of neutron-absorbers consisting of elements or compounds of boron, gadolinium, samarium, cadmium, europium, hafnium, dysprosium and indium, to form a mixture of the powders; (e) isostatically compressing the mixture to form a green body; (f) sintering the green body to form a sintered body; and (g) forming the sintered body into a neutron-absorber body of appropriate shape and dimensions.
