The special features of their oxidation and phase formation in heating ofpericlase-carbon compositions are investigated. It is shown that some of them can be used successfully as an antioxidant component that improves the operational characteristics of periclase-carbon ceramics. It is shown that the imported antioxidant boron-2000 is analogous to amorphous-boron (95 - 85%) preparations, and the latter are recommended for the creation of domestic grades of thermally stable periclase-carbon refractories Полный текст |
