Absorbent neutronic composite material and method for producing same

摘要

The invention relates to a neutron absorbent material and a method of manufacturing such a material. The neutron absorbent material of the invention is a material having a high resistance to corrosion and high mechanical strength. This material is based on hafnium diboride and additionally comprises hafnium dioxide. The method of the invention enables one to reduce the sintering temperature of a composite material based on hafnium diboride. It includes a step that consists of mixing hafnium diboride and hafnium dioxide and a step of sintering the mixture obtained.
