A low melting borosilicate glass frit was used as an adhesion promoter, which enables MnWO 4 to be sintered with in a reasonable sintering temperature range ( 800∼1000 ? C ). The glass was evaluated for glass transition temperature ( T g X) and thermal expansion coefficient( α ). Mechanical property (Vickers hardness), grain growth, the comparison of lattice parameter and pore distribution of sintered MnWO 4 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 MnWO 4 grain, improvement of hardness (until 920 ? C ) and different pore size distribution. Resistance of sintered MnWO 4 varied from 450k Ω to 8.8M Ω 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.
