A METHOD OF MAKING NEUTRON-ABSORBING BRICKS WHICH COMPRISES MIXING WATER WITH CALCIUM BORIDEE POWDER TO FORM A THICK, DRY MUD-LIKE SUSTANCE, PLACING A PORTION OF SAID MUD-LIKE SUBSTANCE INTO A MOLD, COMPRESSING SAID MUD-LIKE SUBSTANCE IN SAID MOLD AT A PRESSURE OF ABOUT ONE TON/IN.2 TO ABOUT TWO TONS/IN.2 TO FORM A "GREEN" BRICK, REMOVING SAID "GREEN" BRICK FROM SAID MOLD BY DISASSEMBLING SAID MOLD, PLACING SAID "GREEN" BRICK INTO AN UNHEATED OVEN, APPLYING HEAT SLOWLY TO SAID OVEN TO A A WARMUP TIME OF ABOUT TWO HOURS TO RAISE THE OVEN TO A BAKING TEMPERATURE OF ABOUT 600*C. AND BAKING SAID BRICK AT A TEMPERATURE FROM ABOUT 600*C. TO ABOUT 900*C. FOR ABOUT TWO TO SIX HOURS, DISCONTINUING THE APPLICATION OF HEAT AND ALLOWING SAID TEMPERATURE TO RETURN SLOWLY TO ROOM TEMPERATURE, SAID BRICK REMAINING IN SAID OVEN UNTIL ROOM TEMPERATURE IS REACHED.
