Study on the Crystallization Kinetics of Complex Slag Glass-ceramic
This study focuses on investigating the crystallization kinetics of complex slag glass-ceramic,utilizing the melting method to prepare the base glass.On the basis of composition research,the main crystalline phase and microstructure of CaO-Mg-Al2O3-SiO2 system composite slag microcrystalline glass samples were analyzed using methods such as differential scanning calorimetry(DSC)testing,X-ray analyzer(XRD),optical microscope,and metallographic microscope.determine the crystallization temperature of the base glass at different heating rates by DSC,so get the optimum heat treatment system.Then,get the crystallization activation energy of the glass-ceramic by calculation:E=221.84 KJ/mol,frequency factor:v=1.980× 1011,kinetic parameters:K(Tp)=0.341,indicating its favorable crystallization propensity.
