In this paper, the compressive strength and in vitro bioactivity of sintered 45S5 bioactive glass scaffolds produced by powder technology and polymer foaming were investigated. The sintering temperature of scaffolds was 975°C. The characterization of scaffolds before immersion in SBF was performed by scanning electron microscopy (SEM) and microtomography (μCT). The scaffolds were also tested for compression,...
This study investigated the influence of particle size distributions on the density, density gradient and strength of uniaxially die-pressed alumina refractories. To design the particle size distributions with a maximum grain size of 1mm, a modified Andreasen model was applied. It allowed the fine and coarse fractions to be adjusted separately. Cylinders were double-action or two-sided die-pressed...
