The Crystallization of $Li_2O-MgO-MgF_2-SiO_2$ Glass System by $B_2O_3$ addition

B$_2$O$_3$의 첨가에 따른 저온 소결기판용 $Li_2O-MgO-MgF_2-SiO_2$

Effects of B$_2$O$_3$ addition in the Li$_2$O-MgO-MgF$_2$-SiO$_2$g1ass system were investigated in order to make glass-ceramics for low temperature firing substrate. Base glass was made by melting at 145$0^{\circ}C$ . This glass was analyzed by THA and DTA to settle nucleation and crystallization temperature. After crystallization. crystal phase and microstructure were absorvated by XRD and SEM. Glass powders were made by water swelling method. Average particle size was 5.44${\mu}{\textrm}{m}$
