Interface topology for distinguishing stages of sintering
网页2017年9月11日 · When two remaining pore channels are pinched off, a single small closed pore is formed at the center of the tetrahedral particle cluster. But, the formed pore disappears quickly.
Porosity changes in progressively pulverized anthracite …
网页2018年8月1日 · Closed pores indicated by the pulverization process. The results show that the total pore, mesopore, and macropore volumes demonstrate a significantly negative power function with median particle size, with the coefficient being determination (R2) of 0.9625, 0.9508 and 0.9554, respectively (Fig. 11 a, b and c).
网页Voids that connect to the surface are referred to as open pores; interior voids inaccessible from the surface are called closed or blind pores. Surface irregularities compose another type of void volume. For example, assume the bulk volume of the brick is determined from linear measurements of its length, width, and thickness.
Porosity: Some characterization techniques - ScienceDirect
网页2023年4月19日 · Abstract. In porous media, porosity performance is critical as it controls fluid flow. In civil construction, geology and others, the connectivity of the porous structure is directly related to this flow.

网页2024年4月15日 · Abstract. Superfine pulverized coal exhibits extraordinary properties in thermal conversion processes like pyrolysis and combustion. The exploration of closed pores is of great significance for studying of the macromolecular structure, and developing advanced clean combustion technologies.
A Full Guide to Powder True Density Analysis - AZoM.com
网页2023年5月26日 · Firstly, true density is a basic parameter of the powder material. The open pores, the closed pores, and the inter-particle voids impact the final performance of the product. The true density value corresponds to chemical composition and its purity, which determines the performance, quality, and application domain of the product.
Properties of Solids - SpringerLink
网页Properties of solids, including particle size, particle size distribution, particle shape, particle density, surface area, porosity, surface charge, flow, and cohesiveness, play a significant role during the processing of powder and determine the quality of the product.
Density and porosity analyses of porous hybrid microparticles ...
网页2024年6月24日 · Porous particles, which generate gas voids as closed pores, are suitable for various applications, such as the fabrication of lightweight, heat-insulating, and coloring materials, owing to their specific properties, such as low densities, high specific surface areas, and low refractive indices.
Microstructure and Pore Characteristics of a Double-Layered Pore …
网页2024年6月4日 · Depending on the structure of the pores in the material, porous metals can be classified as open pore or closed pore types. The properties of the porous metal vary depending on their pore size, pore orientation, and porosity [1,2]. Porous metals with closed pores exhibit high compressive strength, stiffness, buoyancy, and impact absorption .
