Moreover, the assumption that the specific surface area either remains constant or initially increases during dissolution is not always valid. This paper demonstrates that when the particle size distribution has sufficient variance, the instantaneous change in surface area during dissolution can be ...
We have studied the specific surface area, shape, and size of fine particles of isotropic and needle cokes and isotropic graphite. The results demonstrate that, as the average particle size is reduced from 1000 to 1.5 μm, the BET specific surface area of the powders increases from 0.1 to ...
The results show that the Ce-Zr-Ba mixed oxide powder is nano-sized with the particle size of 50nm, and a high surface area of119. 4m~2/g,经1000℃高温处理后,粉体仍能保持纳米级,且分散性好,由于该粉体的高热稳定性和高比表面积*性能,可用作汽车尾气三效催化剂的耐高温保护性涂层材料。
Also, the specific surface area per unit of pore volume (sp), the mean grain size (Gs), and the lithological components were numerically obtained from well-log data and studied in relation to the electric current and hydraulic flow in the JDB reservoirs. 2. Definition, importance, and ...

The BELSORP MAX G is a powerful, compact, and economical model in Microtrac's BELSORP MAX series of BET specific surface area and pore size analyzers. It allows the measurement of gas adsorption isotherms starting from extremely low pressures for the evaluation of micro-, meso- and macrop...
With this purpose, the subsieving techniques of Andreasen pipette, Coulter counter, and laser diffraction methods were compared each other by determining the relationship between specific surface area and particle size distribution. In the tests, the two different standard quartz sand samples (A and ...
