The influence that the zr / ti ratios have on the ceramic crystal structure and its properties are studied through the research carried out about the relative respects of the fabricated samples. the increase of zr / ti ratio can result in the crystal structure transformation from the tetragonal to the rhombohedral, it can also induce the weakness in the stability of the ceramic crystal structure, for example, the drop in the curie temperature. in order to enhance the relative low mechanical quality factor of pzn - pzt system piezoceramics, component addition pb ( mn1 / 3sb2 / 3 ) o3 ( hereafter abbreviated as pms ) are introduced in to form a new psudo - tetragonal system ceramics
為獲得具有高的機電耦合系數kp ，高的機械品質因數qm的高性能壓電陶瓷，採用二次合成法制備了不同zr ti比的鈮鋅酸鉛-鋯鈦酸鉛基（ pzn - pzt ）三元系壓電陶瓷材料，研究了zr ti比變化對陶瓷結構和性能的影響規律，發現zr ti比增大除了可以使陶瓷的相結構由四方相向三方相轉化外，還降低了陶瓷的結構的穩定性，使tc溫度下降。 -
In the processing of single crystal materials, it was found that the sectorial distribution of light and shade appears on the surface, which is the main factor of affecting processing surface quality. therefore starting from the crystal structure, this paper first researched on kdp crystal mechanics characteristics in different crystal plane and orientation through theoretical analysis and nano - indentation experiment, separately calculated the young ’ s modules and shear modules of kdp in different crystal plane, and systematically analyzed the change rule of young ’ s modules and rigidity along with the crystal orientation
在單晶脆性材料的加工中，人們發現加工表面產生明暗相間的扇形分佈，這種明暗相間扇形分佈是影響加工表面質量的主要因素，因此本文從晶體的結構出發，首先對kdp晶體不同晶面、不同晶向的力學性能進行了理論分析和納米壓痕實驗研究，分別計算了kdp晶體不同晶面上彈性模量和剪切模量，並系統地分析了彈性模量和硬度隨晶向的變化規律。 -
Small amount of nb, mn dopants could bring high the qm factor of pms - pzn - pzt based ceramic, so can it bring down the stability of the material crystal structure
在pms - pzn - pzt基陶瓷中微量摻雜nb 、 mn可有效提高陶瓷的機械品質因數，同時促進陶瓷的燒結，得到緻密化的陶瓷。
