According to an aspect, a magnesium fluoride sintered compact includes a disc-shaped magnesium fluoride sintered compact having a through hole passing through a center axis of the disc-shaped magnesium fluoride sintered compact. The magnesium fluoride sintered compact has a relative density of 95% or higher.

Magnesium fluoride sintered compact, method for manufacturing magnesium fluoride sintered compact, neutron moderator, and method for manufacturing neutron moderator

There are provided a method for manufacturing a magnesium fluoride sintered compact to be free from cracks and chipping and to have high relative density, a method for manufacturing a neutron moderator, and the neutron moderator. The method for manufacturing a magnesium fluoride sintered compact includes a powder filling process for filling a magnesium fluoride powder material into a die by tapping, and an intermediate body sintering (pulsed electric current sintering) process for performing pulsed electric current sintering for sintering the filled magnesium fluoride powder material while applying a pulsed electric current thereto, to obtain a magnesium fluoride sintered compact (intermediate body).
