Abstract
In order to provide accurate and semi-real-time information about performances and conditions of various civil engineering structures thick-film resistors are often being used as strain sensors. For that purpose, Ba2Ru2O7 thick resistive films based on compositions with sheet resistivities of 1 kOhm/sq, 10 kOhm/sq and 100 kOhm/sq were evaluated. Resistors were fired at three different peak temperatures (825oC, 850oC and 875oC) and with three different dwelling times (5 min, 10 min and 15 min) in order to correlate influence of firing variables and thick resistive film strain sensitivity by tracking structure-related changes in resistance, gage factor and noise index values. For 10 kOhm/sq composition values of resistance change vs. temperature and temperature coefficient of resistance were measured and calculated.
期刊介绍：
Science of Sintering is a unique journal in the field of science and technology of sintering.
Science of Sintering publishes papers on all aspects of theoretical and experimental studies, which can contribute to the better understanding of the behavior of powders and similar materials during consolidation processes. Emphasis is laid on those aspects of the science of materials that are concerned with the thermodynamics, kinetics and mechanism of sintering and related processes. In accordance with the significance of disperse materials for the sintering technology, papers dealing with the question of ultradisperse powders, tribochemical activation and catalysis are also published.
Science of Sintering journal is published four times a year.
Types of contribution: Original research papers, Review articles, Letters to Editor, Book reviews.
