Effects of different heat-treatment process on the crystallization,phase composition and content,and microstructure of 19MgO-23Al_2O_3-53SiO_2-4TiO_2-2.5B_2O_3(wt%,M-A-S-T-B)were studied by means of differential scanning calorimeter(DSC),X-ray diffraction(XRD)and scanning electron microscope(SEM)techniques.The influence of different nucleation and crystallization time on the microwave dielectric properties were discussed as well.The results showed that,based on the controlled crystallization mechanism of gl...
