Devitrifiable solder glass/$ZrB_2$ sintered composites were prepared by using glass with the composition of $60ZnO-20B_2O_3-10SiO_2-10PbO$(in wt%) and $ZrB_2$, powder as starting materials under the $N_2$atmosphere. $ZrB_2$which the good conduction materials showed sensitive oxidation characteristics, because some parts of the $ZrB_2$in specimens changed into the insulated phase of $ZrO_2$. These Phenomena would be estimated that it caused a few amount of residual oxygen in the furnace and/or specimens and the coordination number change of $B_2O_3$ in the glass. The sintering temperature and the mixed ratios of each phase were control of large ranged the resistivity ranged from 10 to 10$^{3}{\Omega}/cm^2$ orders, and to make a conductible microstructure. From these results, it would be explained that the conduction path of $ZrB_2$particles built up within sintered glass matrix.
