ceramics(UHTCs) are potential candidates as high-temperature thermal insulation materials. However, high thermal conductivity is the main obstacle to the application of porous UHTCs. In order...Low thermal conductivity and high porosity ZrC and HfC ceramics prepared by in-situ reduction reaction/partial sintering method for ultrahigh temperature applicationsHeng Chen1,2,Huimin Xiang2,Fu-Zhi......
Synthesis of porous CaO microsphere and its application in catalyzing transesterification reaction for biodiesel BAI Hai-xin(白海鑫)1, 2, SHEN Xiao-zhen(沈晓真)2, LIU Xiao-hua(刘小花)1, LIU... in catalyzing transesterification reaction for biodiesel. The porous CaO microsphere was synthesized by calcining spherical CaCO3 precursor which was prepared easily by mixing CaCl2 with Na2CO3. The as-prepared......
]. The current inorganic porous materials are divided into two parts: porous ceramics and porous metals. Porous ceramics, which are characterized by high melting points, high corrosion and wear... brittleness, low thermal shock resistance and poor weld ability have limited their applications. Though porous metals have advantages over ceramics, like superior toughness and weld ability, they exhibit......
Processing,Northwestern Polytechnical University摘 要:Porous C/C-SiC composites were prepared through a two-step chemical vapor infiltration process,and a multi-interlayer joint of Li20-MgO-Al2O3-SiO2(LMAS) was applied to join C/C-SiC composites and lithium aluminum silicate(LAS) glass ceramics by means of a vacuum hot-pressing technique.Plenty of SiC......
