The main purpose zinc oxide and particle size measurement

Most particles,[link widoczny dla zalogowanych], the frequency distribution of the total 15.0l0%. Another short peak particle size is very large, not fully distributed Clusters (aggregate), did not meet requirements of nano-scale, in which particle size from 2976nm to 3409nm aggregate between the highest frequency of 0.585 percent and the overall distribution. 3.3 The results of electron microscopy image analysis by transmission electron microscope image acquisition, shooting pictures of particles obtained as shown in Figure Five. Size distribution of computer software to the results of statistical calculations shown in figure VI. Total number of particles the average particle size = 394 = l7, 194nm a DA sister. Hu industry: December First Figure V transmission electron microscope to image {】 / I 【'Fig. Median diameter = 15.0nm average particle size = 16.5nmf (D) (%, nm) I588} 07.214421628 +836 D (nm) Figure VII X-ray small angle scattering analysis of the results of particle size distribution of nanometer ZnO 4 . Conclusion (1) laser light scattering and photon correlation method using the same method of dispersing agent added samples measured, the measured particle size is more granular powder materials, and photon correlation analysis laser light scattering measurements than the accuracy of higher can be measured a smaller particle size. (2) Nano ZnO choice of dispersing agent should be used as dispersant sodium hexametaphosphate, distributed evenly and fully, the effect is significant. Trough and the stick together with further prolonged ultrasonic ultrasonic dispersion, the ultimate measurement of efficiency of industrial paper Clippings (3) the results of TEM are the main method is a particle, the individual grains and the aggregate of the statistics, X-ray small angle scattering particles get is a statistical value, so the results are basically two methods of measurement is similar to (4 ) method and electron microscopy images small angle scattering X-ray measured results of nano-scale particle size can be obtained. The laser light scattering analysis and photon correlation measurements by the dispersion effect of other factors greatly, the accuracy is poor,[link widoczny dla zalogowanych], but as long as they do it before the full dispersion of the sample, measurements can still reach the required scales.
