The confidence interval in RH measuring bar restricted by equipment accuracy was no worse than ±1% and in temperature measuring bar ±0.5°C. Results and discussion Bulk dielectric MgAl2O4 ceramics, which are used for the preparation of humidity-sensitive thick-film layers, are characterized by tri-modal pore size

distributions (Figure 2). This distribution covers the charge-transferring micro/nanopores (the first peak centered near 4 nm) depending on sintering conditions, water-exchange inside-delivering or communication mesopores (the second peak centered near 65 nm), and water-exchange outside-delivering macropores (the third peak centered near 350 nm) depending on the specific surface area of milled MM-102 cost MgO-Al2O3 powder [24]. According to Kelvin equation [25], for capillary condensation processes of humidity in ceramics and their thick film at room temperature in the investigated range of RH (20% to 99%), the cylindrical pores with a radius from 1 to 20 nm are required. Meso- and macropores with radius more than 20 nm (the second and third

peaks) are not involved in the capillary condensation process, but they ensure the effective transfer of water into ceramic bulk. Thus, the presence of pores in each area provides effective adsorption and desorption humidity processes in material bulk.

The grains are integrated into agglomerates. Spherical and cylinder pores are located near the grain boundaries. Average grain size for these ceramics is approximately 300 – 500 nm. Figure 3 SEM micrograph of MgAl 2 O 4 ceramics sintered at 1,300°C for 5 h (1 – grain, 2 – grain boundaries, 3 – pore). Typical pore size distribution for temperature-sensitive bulk ceramics Racecadotril are shown in Figure 4. It differs significantly from the pore size distribution for humidity-sensitive ceramics. This distribution covers

only charge-transferring pores centered near 3.5 and 5.5 nm. But the amount of such pores is higher in comparison with MgAl2O4 ceramics. Figure 4 Typical pore size distributions for temperature-sensitive ceramics. In respect to the SEM data, the microstructure of temperature-sensitive ceramics is characterized by separate pores with 1 to 3 μm in sizes (Figure 5). White NiO film appears as bright layer of 10-μm thickness on the grain surface of these samples. The grain structure of ceramics attains monolithic shape. Individual pores of relatively large sizes (near 3 to 5 μm) are observed in these ceramics, the NiO appearing as uniform layer on the whole ceramic surface. The observed additional NiO phase is non-uniformly distributed within ceramic bulk, being more clearly pronounced near the grain boundaries [12].
