Abstract (en)
[origin: WO2004031089A1] The invention relates to crystallisable aluminosilicate magnesium-containing glass which is used for producing extremely solid and break-resistant glass-ceramics having an easily polished surface. The inventive crystallisable glass contains 5-33 mass % of SiO2, 25-40 mass % of Al2O3, 5-25 mass % of MgO, 0-15 mass % of B2O3, 0.1-30 mass % of Y2O3, Ln2O3, As2O3 and /or Nb2O5 and 0.1-10 mass % of P2O5.
