and service characteristics than the symmetric ones. In our preliminary studies the possibility of obtaining sintered porous materials with gradual structure by sedimentation of metallic and ceramic powders was demonstrated. Zirconium silicate (ZrSiO4) particles were used for the manufacturing of the porous supports, and mullite powder was deposited by sedimentation in order to achieve the active......
Synthesis of Calcium Chloroborate Whiskers Via Sedimentation and Sintering Process朱东海1,2,NAI Xueying2,兰生杰1,3,DANG Li1,3,LIU Xin2,李武21. State Key Laboratory of Plateau Ecology and Agriculture, Qinghai... chloroborate(Ca2B5O9Cl) whiskers with uniform diameter have been fabricated by a two-step process. The precursor was firstly prepared by the sedimentation reaction between CaCl2, H3BO3 and Na OH......

Rapid recovery of polycrystalline silicon from kerf loss slurry using double-layer organic solvent sedimentation methodPeng-fei Xing1,Jing Guo1,2,Yan-xin Zhuang1,3,Feng Li1,Gan-feng Tu11. School... to the kerf loss in the wafer slicing process.To efectively recycle polycrystalline silicon from the kerf loss slurry,an innovative double-layer organic solvent sedimentation process was presented......
solubility, reactivity and sedimentation, of ZnO and ZnS in a Na2CO3-NaCl molten salt used for Sb smelting was investigated in the temperature range of 700-1000°C. The saturated amount of dissolved ZnO... molten salt increased with increasing temperature, and the content of ZnS was 0.53% at 1000°C. In addition, ZnS reacted with Na2CO3 above 900°C to give ZnO. The sedimentation rates of these three species......
