Método para fabricar una pieza compacta sinterizada de fluoruro de magnesio y método para fabricar un moderador de neutrones
Método para fabricar una pieza (ds) compacta sinterizada de fluoruro de magnesio, comprendiendo el método: llenar con un material de polvo de fluoruro de magnesio mediante golpeo un troquel; y realizar sinterización por corriente eléctrica pulsada para sinterizar el material de polvo de fluoruro de magnesio llenado mientras se aplica una corriente eléctrica pulsada al mismo, para obtener una pieza compacta sinterizada de fluoruro de magnesio, en el que la velocidad de calentamiento del troquel es de 1ºC/min a 7ºC/min.
The present invention provides a neutron moderator that moderates neutrons, the neutron moderator comprising: a first intermediate layered body in which a plurality of disc-shaped magnesium fluoride sintered compacts are layered; and a second intermediate layered body in which the disc-shaped magnesium fluoride sintered compacts are layered, the second intermediate layered body being layered on the first intermediate layered body and including: a hole in the disc-shaped magnesium fluoride sintered compacts; a tapered surface surrounding the hole; a bottom surface; and a vertical inner wall disposed in a disc-shaped magnesium fluoride sintered compact disposed in a bottom of the second intermediate layered body , the vertical inner wall extending in a vertical direction through the tapered surface and the bottom surface of the disc-shaped magnesium fluoride sintered compact. The top surface 2A of the first intermediate layered body 2 and the bottom surface 3B of the second intermediate layered body 3 are joined together at the neutron moderator assembling process. The top surface 3A of the second intermediate layered body 3 becomes the top surface 1A of the neutron moderator. In addition, the bottom surface 2B of the first intermediate layered body 2 and the top surface 4A of the third intermediate layered body 4 are joined together. The bottom surface 4B of the third intermediate layered body 4 becomes the bottom surface 1B of the neutron moderator. The neutron moderator 1 is manufactured by layering the first intermediate layered body 2, the second intermediate layered body 3, and the third intermediate layered body 4.
