| 1 | Crystallization Behavior of High Purity Fused Magnesia显示文摘The chemical composition and microstructure of Tibetan microcrystalline magnesite were studied by means of XRF,XRD and FESEM. It is found that the microcrystalline magnesite has uniformly distributed grains,mostly in the range of 2-4 μm,and the MgO content is47. 80%. In fused magnesia,the druses are colorless transparent periclase megacrysts without impurity,while the crust sand is white,with a high MgO content up to97%-99%. The periclase crystals are big,appearing as faced and step-growth morphology. Massive secondary long columnar periclase is crystallized. | LI Xuejun GAO Zhenxin YAN Guanghui ZHANG Wei FU Qiuhua | 2017 | China's Refractories2017，26，2： | 2 |

| 5 | Phase Relationship at Subsolidus Temperature of MgO-MgAl2O4-ZrO2 Subsystem显示文摘Three groups of cylinder specimens(φ10 mm×10 mm)with 20%,30%and 40%(by mass,the same hereinafter)of ZrO2,were prepared using analytically pure MgO,Al2O3 and ZrO2 powders as the starting materials.The specimens were fired at 1600℃for 5 h,1700℃for 0 h and 1800℃for 7 h,respectively.The microstructure of the MgO-MgAl2O4-ZrO2 subsystem was studied by FESEM.The results show that(1)in the temperature range of 1600-1700℃,solid phase reactions happen in the MgO-MgAl2O4-ZrO2 subsystem,leaving three phases:periclase,spinel and ZrO2(solid dissolving with Mg2+)co-existing;spinellization affects the densification;(2)the specimen with 40%ZrO2 fired at 1800℃has heterogeneous melting microstructure;some areas form typical ternary eutectic MgO-MgAl2O4-ZrO2 with composition of MgO 35.2%-37.2%,Al2O324.2%-26.6%,and ZrO237.2%-39.8%. | GAO Zhenxin | 2020 | China's Refractories2020，29，1： | 0 |
| 6 | Microstructure Study on Oxidation of Zirconium Diboride显示文摘The oxidation behaviors of fused zirconium diboride and chemosynthetic zirconium diboride as well as morphology and composition of their oxidation products were researched by FESEM-EDS and XRD.The two kinds of zirconium diboride were heated at 700℃,900℃,1100℃and 1300℃for 3 h in air,respectively.The results show that Zr02 and B203(Ⅰ)are generated from the chemosynthetic zirconium diboride oxidized at 700℃for 3 h or the fused zirconium diboride oxidized at 800℃for 24 h;B203(Ⅰ)dissolves into water and then H3B03 crystallizes. | GAO Zhenxin LIU Cheng | 2019 | China's Refractories2019，28，4： | 0 |
| 7 | Temporal Behaviours of Stimulated Rayleigh-Wing Scattering at Non- and Quasi-Equilibrium of Orientational Distribution显示文摘The temporal behaviours of stimulated Rayleigh-wing scattering,at quasi-equilibrium and non-equilibrium of the molecular orientational distributions,are reported in this letter.The experimental results also show the relaxation time of molecular orientation in high alignment is longer than 80 picosecond. | WANG Hezhou ZHENG Xiguang MAO Weidong YU Zhenxin GAO Zhaolan | 1995 | Chinese Physics Letters1995，12，9： | 0 |
