CERAMIC BODY AND CERAMIC BODY MANUFACTURING METHOD

摘要

To present a ceramic body the density of which is great, that is high strength, and that exhibits a superior radiation shielding effect, and a manufacturing method for this. A ceramic body in which by firing clay into which ferrite powder has been mixed at a proportion of 60 wt% after being formed into a specified shape, the density after firing has been made 3.5 g/cm3 and the radiation shielding effect has been enhanced is obtained. For the ferrite powder, one that is expressed by the compositional formula: AO ・nX2O3 (however, it should be noted that in said compositional formula, A is one type or more of an element selected from among Mg, Ca, Mn, Co, Ni, Cu, Sr, Ba, or Pb, X is one type or more of an element selected from among Fe, Co, or Ni, and n is a mol ratio that is defined as an integer from 1 to 9) is used.
