Bioreactive materials, used as basic materials or as covering materials for implants and prostheses in the medical, dental and veterinary fields, obtained by melting a mixture of 20 to 50% by weight of Si0 2 , 15 to 25% in weight of CaO, 5 to 10% by weight of P 2 0 6 , 15 to 25% by weight of Na 2 0 and 3 to 15% by weight of Al 2 O 3 or their metal precursors giving by fusion equivalent amounts into oxides. |
