Effects of (Mg1/3Sb2/3)4+ substitution on the structure and microwave dielectric properties of Ce2Zr
Ce2[Zr1-x(Mg1/3Sb2/3)x]3(MoO4)9 (0.02 ≤ x ≤ 0.10) ceramics were prepared by the traditional solid-state method.A single phase,belonging to the space group ofR(3)c,was detected by using X-ray diffraction at the sintering temperatures ranging from 700 to 85
Microstructure refinement-homogenization and flexural strength improvement of Al2O3 ceramics fabrica
In this study,the chemical precipitation coating (CP) process was creatively integrated with DLP-stereolithography based 3D printing for refining and homogenizing the microstructure of 3D printed Al2O3 ceramic.Based on this novel approach,Al2O3 powder was
Structure evolution,dielectric,and conductivity behavior of(K0.5Na0.5)NbO3-Bi(Zn2/3Nb1/3)O3 ceramics
(1-x)K0.5Na0.5NbO3-xBi(Zn2/3Nb1/3)O3 ((1-x)KNN-xBZN,x =0.010,0.015,0.020,0.025,and 0.030) lead-free ceramics were fabricated via a traditional solid-state method.The crystal structure,microstructure,dielectric,and conductivity behavior of this system were

It is a very difficult work to sinter K0.5Na0.5NbO3 (KNN)-based materials with good reduction resistance in strong reducing atmosphere.0.945K0.48Na0.52Nb0.96Ta0.04O30.055BaZrO3 +0.03ZrO2 + y mol％MnO (KNNT-0.055BZ + 0.03Zr + yMn) ceramics sintered in reduc
新疆乌恰县范围内,在煤田地质勘查活动中发现有铀元素富集成矿现象,本文通过矿床地质特征分析和巴什布拉克铀矿床的对比,分析了成矿条件,总结出含矿为下白垩统克孜勒苏群下段,成矿类型为层间氧化带型.
矿山开拓系统对矿山生产具有长远影响,是决定矿山基建工程量、基建投资、基建工期、经营费用高低的最关键因素之一,因此择优选择合理的矿山开拓系统十分重要.某露天转地下铁矿开采生产规模为年产300万吨.初步选择竖井开拓方案,在竖井开拓方案中,进一步优化,根据矿山的工程地质情况结合经济、技术比较综合分析,选择最优的西主井方案.
新疆是全国煤炭资源的富集区,开采出来的煤炭通过制样并经煤质化验分析后,按照中国煤炭分类标准,根据分类参数指标进行煤种判断.黏结指数就是其中一种指标,用于烟煤的分类.本文通过对比标准GB/T5447-1997和GB/T5447-2014在技术上的变化,分析影响黏结指数测定的因素,给出了提高试验准确性和试验效率的建议,对试验人员具有借鉴指导作用.
