METHOD OF STABILISING RARE-EARTH IONS IN TRIVALENT STATE IN SILICATE GLASS AND COMPOSITES

摘要

FIELD: chemistry.SUBSTANCE: method of stabilising trivalent ions of cerium (Ce), praseodymium (Pr) and divalent europium (Eu) in silicate glass and glass composites in a glass melting mixture includes adding silicon carbide in a ratio to cerium, praseodymium or europium oxides in the range of 2/1 to 1/3. A premix of silicon carbide and cerium, praseodymium or europium oxides is prepared first and then mixed with components of the mixture.EFFECT: stabilising trivalent ions of cerium and praseodymium and divalent europium in silicate glass and glass composites by adding silicon carbide.3 dwg, 1 tbl
