“…Some performance tests have been presented in this paper, but a large mock-up test program should be performed to reduce development risk. crystallization of ortho-and meta-silicate without introducing pores and cracks [14], and the development of oxide-doped Li 2 TiO 3 for better grain size and chemical stability [15]. Their impacts on blanket performance, such as the occurrence of a small amount of fragmented particles, have yet to be quantified.…”

“…And porous microspheres have been widely used in the potential applications such as storage, delivery, separation, catalysis and heat insulation [4][5][6][7][8]. So far, various porous microspheres with special characteristics, such as porous spheres with a single cavity, porous spheres with multiple shells and porous sphere with multicavities, have been fabricated by templating method [9], emulsion processing [10,11], high temperature smelting [12,13], layer-by-layer self-assembly technique [14] and so on, wherein porous spheres with multicavities as an important class of porous sphere have gained growing attention. However, the adopted devices or procedures of the aforementioned methods are somehow complicated.…”

Porous zirconia (ZrO 2 ) microspheres with incontinuous multicavities were prepared via emulsion method combined with phase separation in the presence of polyvinylpyrrolidone (PVP). The morphology of the microspheres is derived from the spherical oil droplets by high-speed shearing and the sol-gel reaction on the droplets, while the PVP acts as a phase separation inducer to form incontinuous multicavities inside the microspheres. The addition of PVP does not change the particle size distribution and smooth surface morphology of the microspheres, while the size of cavities inside microspheres increases gradually with the increase in PVP amount. The particle characteristics, phase transformation and cavity formation mechanism of porous ZrO 2 microspheres are analyzed in detail.

“…An additional advantage of pebble fabrication by melting is the much simpler reprocessing. For the pebbles, fabricated by a melt-spraying process [12,13], the direct remelting without any additional wet-chemical recycling step has been proposed as a simpler reprocessing process. Problems with this method are internal stresses in the pebbles that lead, in some cases, to cracks and thus to a deviation in mechanical properties.…”
