Creators

Description

This material consists of a mortar comprising granules of a mineral composite of boron, aluminous cement and water, bonded chemically. The boron content is at least 0,6. 1022 atoms/cm3 and the hydrogen content is at least 1,42.1022 atoms/cm3. Preferentially, the boron ore material is colemanite. The present material can be used in the realization of shielding-walls, of coatings and elements of installations of a sub-critical medium
