             abstract = "The main objective of this work is to study and characterize 
                         porous ZrO2-TiO2 films on alumina substrates that will be used for 
                         the production of porous ceramic sensors for the monitoring of air 
                         humidity in environments subject to the incidence of solar 
                         radiation. For the production of the films the dip coating 
                         technique was adopted. A viscosity study was performed to obtain 
                         stable suspensions of ZrO2-TiO2 in isopropyl alcohol with the 
                         para-aminobenzoic acid deflocculant (PABA), at concentrations of 
                         10, 12.5 and 15% by weight of solids. X-ray diffraction (XRD) 
                         characterizations were performed for the identification of 
                         crystalline phases, morphological analyzes by scanning electron 
                         microscopy (SEM) and chemical analyzes by energy dispersive X-ray 
                         spectroscopy (EDS). The results allowed to determine the minimum 
                         value of viscosity and amount of deflocculant to stabilize the 
                         suspension. The sensor elements in the form of 1:1 (weight) 
                         ZrO2-TiO2 porous films showed great potential to be used as 
                         sensors for the measurement of relative humidity the size and 
                         distribution of desirable pores in the porous film for application 
                         as moisture sensors was obtained with 12.5 and 15 % by weight 
                         ZrO2-TiO2.",
