Hi Masters. I'm searching for control rod materials and so far I got the ones listed below. I know that the material selected for control rods should have a good absorption cross section for neutrons and have a long lifetime as an absorber. I just wonder the materials and compounds used in control rods other than listed below. - Boron ( as B-10 and B-11) - Boron carbide (B4C) - Boron-stainless steel (B-SS) - Cadmium (Cd-113) - Silver (Ag-105, Ag-107) - Hafnium (Hf-174, Hf-176, Hf-177, Hf-178, Hf-179, Hf-180) - HfB2 - Indium (In-115) - Europium - Stellite (cobalt-chromium alloys) - Gd2O3 (Gadolinium) - Eu2O3 (Europium oxide) - Dysprosium titanate (Dy2TiO5 - Is this correct ? Some sources says it is Dy2TiO7 and some other says it is Dy2TiO9) Please inform me if any of the listed materials are wrong or if there any other materials. I suppose there should be more compounds but I can just arrange the ones listed. Also, if anyone knows please indicates the percentage of the compounds. For an example, if I am correct, there exist - Ag-In-Cd as 80% Ag, 15% In, and 5% Cd Best.
