Abstract
A low melting borosilicate glass frit was used as an adhesion promoter, which enables <TEX>$MnWO_4$</TEX>to be sintered with in a reasonable sintering temperature range (<TEX>$800∼1000^{\circ}C$</TEX>). The glass was evaluated for glass transition temperature (<TEX>$Τ_{g}$</TEX> X) and thermal expansion coefficient(<TEX>$\alpha$</TEX>). Mechanical property (Vickers hardness), grain growth, the comparison of lattice parameter and pore distribution of sintered <TEX>$MnWO_4$</TEX> with the frit were methodically discussed. As sintering temperature increased, a typical liquid phase sintering showed the rapid grain growth and high densification of X<TEX>$MnWO_4$</TEX>grain, improvement of hardness (until <TEX>$920^{\circ}C$</TEX>) and different pore size distribution. Resistance of sintered <TEX>$MnWO_4$</TEX>varied from 450k<TEX>$\Omega$</TEX> to 8.8M<TEX>$\Omega$</TEX> under the measuring humidify ranging from 30 to 90%. Thus, the results will contribute to the application of glass frit containing sensor materials and their future use.
