摘要：
[Object] Provided are inorganic fibers or inorganic flakes having excellent neutron shielding properties.
[Solution] When a formulation including: a base component containing SiO 2 and Al 2 O 3 as main components (provided that the mass ratio occupied by the sum total of SiO 2 and Al 2 O 3 in the base component is 0.60 or more); and a neutron shielding component composed of at least one of gadolinium, gadolinium oxide, samarium, samarium oxide, cadmium, or cadmium oxide, are blended at the proportions of 50 to 90 parts by mass of the base component and 10 to 50 parts by mass of the neutron shielding component and melted, satisfactory amorphous inorganic fibers and inorganic flakes were obtained.
