particle microstructure
1.Precipitation conditions, such as molar ratio of ammonia to uranium, uranium content, ammonium hydroxide content, temperature, rate of adding uranium, etc. , have influences on ADU particle size, its microstructure and the properties of UO2 powder.
2.The influences of WC content upon wear resistance of sprayed coating were studied through testing of macroscopic hardness,low-stress abrasive particle wear resistance and analyse of microstructure of sprayed coating.
3.The influence of the particle size distribution of compound mineral admixture on strength and microstructure of cement mortar
4.The influence of particle size of the starting materials, reaction temperature and holding time are studied experimentally. The phase composition and microstructure of the product are analyzed by means of XRD SEM and EDS.
5.The microstructure of antibacterial zeolite was investigated by XRD, FTIR, SEM, BET and particle size analysis, and antibacterial performance was tested according colony number.
6.It is shown that the microstructure of Al-Ti-C master alloy consists of Al matrix, acicular and chiplike TiAl3 phase and TiC particle cluster; TiC particle is a kind of compound with non-chemical metric ratio and its X is 0.5～0.8;
7.It is analyzed comparatively that the sort,hardness,microstructure,particle shape,size distribution,macrostructure,density of an abrasive for shot blasting steel structures during their coating and anticorrosion,i. e. the pretreatment of steel.
8.Ni-Zn-Cu ferrites nanoparticles were successfully prepared by microwave assisted soft chemical processing method,and phases,thermal properties,size analysis and microstructure of the as synthesized nanoparticles were investigated by XRD,TG-DTG,laser particle sizer and TEM.
9.The yield and microstructure of CNF changed with the active metal composition, which was attributed to the surface reaction between CO and active metal (alloy) together with the carbon diffusion mode on/in the metal particle.
10.The microstructure of the composites was more even. The HREM、TEM observation and electron diffraction analysis showed that the new phase generated around the α-Al2O3 particles. The interfaces between the phase and Al2O3 particle are very clear and bonded well.
