THEORETICAL PRECONDITIONS OF NEW KINDS OF NUCLEAR PROTECTIVE METAL COMPOSITE MATERIALS DEVELOPMENT BASED ON FERRIC AND BISMUTH OXIDES CAPSULATED INTO METALLIC ALUMINUM MATRIX
Matyukhin P.V.
Nowadays there are topical tasks in the nuclear protective building materials science for working out new kinds of materials with high nuclear protective and strength characteristics, efficient under conditions of dynamic, alternate temperatures and combined radiation loads, resistant to high repeated temperature drops.

Such materials can be presented by composite materials combining plastic metallic skeleton (aluminum, lead, copper, tin etc.) and solid metallic and nonmetallic reinforcing components both of natural and artificial origin (granite, basalt, limestone, dolomite, quartzite, marble, metallurgical slag, ashes, expanded clay, ferric oxide systems and others) [1]. Particularly, there is a practical interest to elaboration of the metal-composite material based on highly dispersed ferric oxides (magnetite, hematite) and bismuth oxide capsulated into metallic aluminum matrix.

The use of ferric oxide fillers will allow to increase physico-mechanical and nuclear protective properties of the composite (resistance to highenergy fields of γ-radiation impact); bismuth will enhance the ability to scatter heat neutrons almost without absorption; aluminum matrix application as a binding agent would give unique properties of aluminum: high degree of workability (the material will be well pressed and can take plastic deformation), elevated heat conductivity and ability to reflect heat flows.

On my opinion, further development of scientific aspect of elaboration and manufacture of such metal composite materials and, as a consequence, the design of modern nuclear protective engineering constructions on its base would play a great role in the field of nuclear protective building materials science.
