The crystallization behaviour of SiO2-MgO-3CaO-P2O5-Al2O3-ZrO2 glass was studied using glass samples prepared by melting reagent grade SiO2, MgO, Ca5(PO4)3OH, P2O5, Al2O3 and ZrO2. DTA and XRD analysis revealed the crystallization of whitlockite, anorthite and baddeleyite phases. The crystallization kinetics was studied by applying the DTA measurements carried out at various heating rates. The activation...
W pracy badano stopień skrystalizowania szkieł z wykorzystaniem termicznej analizy różnicowej w procesie ich kierowanej krystalizacji. Skład chemiczny szkieł wyjściowych został dobrany w sposób umożliwiający otrzymanie w późniejszych tworzywach szklanokrystalicznych monomineralnej fazy piroksenowej, przy zmieniającym się stosunku wolastonitu do diopsydu w granicach od 0,5 do 4. Otrzymano szereg krzywych...
