This book was released on 1995 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In recent years, the importance of monitoring combustion processes for fuel efficiency and pollution control has necessitated the development of reliable gas sensors for high temperature in situ detection. Semiconductor gas sensors have been developed for a wide range of reactive gases, but are typically nonselective to any particular gas in gaseous mixtures. The objective of this research was to develop fast-responding solid-state sensors for the selective detection of CO gas at elevated temperatures, as well as to understand and characterize the associated sensing mechanisms. From preliminary dc electrical resistance measurements, the sensing properties of various semiconducting oxides were investigated, and Mo03- and Ti02-based systems were selected as candidate sensor materials. Mo03 was found to display an ON/OFF-type sensing behavior. X-ray photoelectron spectroscopy (XPS) results indicated that the sensitivity could be attributed to the surface reduction of Mo03 to the Mo02 phase. The Ti02 sensor displayed a gradual drop in electrical resistance with increasing CO concentration but suffered from H2 interference. Two different mechanisms were proposed (based on recovery characteristics) to describe the sensitivity of Ti02: a surface-controlled mechanism for CO, supported by XPS data, and a bulk-diffusion controlled mechanism for H2. Through second phase additions of 10 wt% Y203 and 10 wt% Al203, the sensor was made selective to CO and H2, respectively with no interference from NOx. Fe and Pd catalyst additions improved both the response time and the lower limit of CO detection. A sensor device of (Ti02-10 wt% Y203)-5 wt% Pd was developed with optimized geometry, electrode configuration, and processing conditions. A prototype device was sucessfully tested in an automobile engine for over 50 cycles, responding quickly and reversibly under revving and idling conditions. Immittance spectroscopy (IS) was employed to characterize the electrical behavior of Ti02. By extracting the electrical parameters through lumped parameter/complex plane analysis, the sensing behavior was found to be grain boundary-controlled, with sensitivity determined by electrical barriers at the intergranular contacts. Upon exposure to CO gas, these barriers are effectively lowered, and the depletion region width decreases. The observed decrease in electrical resistance and increase in grain boundary capacitance provided evidence in support of this proposed mechanism.

This book was released on 2013-06-30 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ceramic powder prepared from the mixture of SiO₂, KNO₂ and KNO₃ have been characterized for NTC behavior and the same have been used as sensor material in the form of a thin metal cable to detect over-heating. These materials have mega ohm resistance at room temperature and showed exponential drop in resistance with the rise in temperature over a temperature range of 100-400 ˚C. The material was sintered at 800˚C for 2 h resulting in good bonding strength. The electrical characters were tested by plotting graph between temperature and resistance being main parameters of entire sensor system in the temperature range of 110˚C to 370˚C. Several other important characteristics like B value, Activation energy, Temperature co-efficient were also calculated for checking the electrical characterization of sensor material. The material characterization was also conducted with help of different techniques. XRD result confirmed about the spinal type crystal structure of the sample mandatory for electrical behavior required for NTC sensors. SEM study showed the morphology of material which is discrete grains good for conductivity at high temperatures. The ceramic material thus synthesized can be used in over heating detection application in several fields.

Book excerpt: From the Author's Preface Ceramic sensors have been in use for more than thirty years. Since ceramics exhibit a number of specific characteristics that enable their cost to become lower and their reliability to increase, they have occupied a significant position in sensor technology. This is why many companies and universities have directed their efforts towards investigating and developing new ceramic sensors and expanding their areas of application. To the best of our knowledge.., there [has been] no book treating different sensors on the basis of their common physical and chemical properties, technological principles, and applications. This book [is] a detailed survey of ceramic sensors and a generalization of the results achieved in this field so far. Ceramic sensors for different physical quantities are discussed without going too deep into theory... The concept of ceramic sensors includes all sensors that are produced using ceramic technology. It also covers thick film sensors, since from a structural and technological point of view, they can be regarded as a variety of ceramic sensors. The subject of scientific research in this book is humidity, gas. temperature, and pressure sensors on the basis of semiconductor and dielectric ceramic materials and solid electrolytes. Special attention is paid to the physical and chemical, as well as the technological, bases of ceramic sensors, their classification, the types of materials used... , the methods of controlling their parameters and characteristics, the areas of application, and the electric circuits for connecting the sensors.

Download or read book Synthesis and Characterization of Novel Polymer-ceramic Nanocomposites written by Phillip Byron Messersmith and published by . This book was released on 1993 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manuscript describes the synthesis and characterization of novel polymer-ceramic nanocomposites (organoceramics) based on various water soluble polymers and calcium aluminate hydrates. Synthesis of these materials involves the aqueous precipitation of the inorganic crystals in the presence of polymer. The presence of polymer during crystallization often leads to changes in particle morphology, and in some cases intercalation. The organoceramics based on poly(vinyl alcohol) (PVA) and $\rm CaO{\cdot} Al\sb2O\sb3{\cdot} 10H\sb2O$ (CAH$\sb{10})$ were found to exhibit retarded phase transformation kinetics and unique particle morphologies. Intercalation of PVA between layers of $\rm\lbrack Ca\sb2Al(OH)\sb6\rbrack\sp+\lbrack(OH){\cdot} 3H\sb2O\rbrack\sp-$ occurred during crystal growth, resulting in an organoceramic containing up to 40% polymer by weight. Polymer intercalation resulted in an expression of the interlayer by approximately 10 A, consistent with the formation of a double layer of PVA chains across each interlayer. Thermal degradation of the inorganic and polymeric components of the organoceramic occurred at higher temperatures than the individual materials. Compressive strength of PVA organoceramic powder compacts was significantly higher than that of $\rm\lbrack Ca\sb2Al(OH)\sb6\rbrack\sp+\lbrack(OH){\cdot} 3H\sb2O\rbrack\sp-$ compacts, possibly reflecting substantial differences in particle morphologies.
