This paper reports the properties, mechanism and preparation method of MgCr 2 O 4 -TiO 2 humidity sensor and its typical application in microwave oven, air conditioner and dryer. Physical Properties of MgCr_2O_4-TiO_2 Ceramics The porous structure of MgCr_2O_4-TiO_2 has good high-temperature mechanical and thermal properties. However, the high chromium oxide is not easy to sinter into a high density, therefore, the sintered product is generally porous structure. Table 1 lists its typical porous sintering
