WIPO Patent Application WO/2022/145401
Kind Code:
A1
Abstract:
[Problem] To provide inorganic fibers or inorganic flakes having excellent neutron shielding properties. [Solution] Highly amorphous inorganic fibers and inorganic flakes that are obtained by mixing a base component, said base component containing SiO2 and Al2O3 as principal elements (provided that the ratio by mass of the sum of SiO2 and Al2O3 to the base component is 0.60 or more), with a neuron shielding component comprising at least one of gadolinium, gadolinium oxide, samarium, samarium oxide, cadmium and cadmium oxide at a ratio of 50-90 parts by mass of the base component and 10-50 parts by mass of the neuron shielding component, and then melting the resultant mixture.
