摘要

本研究旨在确定钼和钴添加剂如何影响 Pb(Zr0.52Ti0.48)O3.粉末最初是通过湿化学工艺制成的。煅烧粉末的 XRD 检查表明,随着掺杂剂浓度的增加,四方相迅速减少,同时让位于斜方相。随着掺杂剂浓度的增加,烧结圆片的 SEM 分析表明,最初在 Zr 位点的晶粒大小发生了很大变化。PZT 压电特性的详细研究 在制作和检测的样品中,可以看到压电电荷系数、机电耦合系数、谐振频率和机械品质因数发生了显著变化。方差分析用于评估添加剂对共振频率的影响,结果表明钼和钴的添加对共振频率有显著影响。

Analysis of variance (anova) of the influence of molybdenum and cobalt additives on piezoelectric, dielectric and ferroelectric properties of Pb(Zr0.52Ti0.48)O3
This study aims to determine how molybdenum and cobalt additives affect the structural and electrical characteristics of Pb(Zr0.52Ti0.48)O3. by substituting zirconate and titanate with molybdenum and cobalt, individually or in combination, in the range of 0–2%. The powders were initially made in order to achieve this via a wet chemical process. They were then calcined at 800 °C for 4 h. The calcined powders' XRD examination indicates that the tetragonal phase rapidly diminishes with dopant concentration and concurrently gives way to rhombohedral phase. With an increase in dopant concentration, a SEM analysis of sintered discs showed a considerable change in grain size initially at the Zr site. Detailed investigations of the PZT's piezoelectric properties Significant changes in the piezoelectric charge coefficient, electromechanical coupling coefficient, resonant frequency, and mechanical quality factor can be seen in the samples that were created and examined. Analysis of Variance was used to evaluate the impact of additives on resonance frequency, and the results revealed that the addition of molybdenum and cobalt has a significant impact on resonance frequency.

期刊介绍: Journal of Engineering Research (JER) is a international, peer reviewed journal which publishes full length original research papers, reviews, case studies related to all areas of Engineering such as: Civil, Mechanical, Industrial, Electrical, Computer, Chemical, Petroleum, Aerospace, Architectural, Biomedical, Coastal, Environmental, Marine & Ocean, Metallurgical & Materials, software, Surveying, Systems and Manufacturing Engineering. In particular, JER focuses on innovative approaches and methods that contribute to solving the environmental and manufacturing problems, which exist primarily in the Arabian Gulf region and the Middle East countries. Kuwait University used to publish the Journal "Kuwait Journal of Science and Engineering" (ISSN: 1024-8684), which included Science and Engineering articles since 1974. In 2011 the decision was taken to split KJSE into two independent Journals - "Journal of Engineering Research "(JER) and "Kuwait Journal of Science" (KJS).
