Times Cited Count：56 Percentile：78.79(Materials Science, Ceramics)Several types of Si-based ceramic fibers have been prepared using an organic-to-inorganic conversion process. In this article, the preparation, microstructure, and high-temperature stability of SiC-based ceramic fibers prepared from polycarbosilane of an organosilicon polymer are reviewed. The first fiber produced was an amorphous Si-C-O fiber, next was a low-oxygen content Si-C fiber, and finally, a nearly stoichiometric SiC fiber was developed. These fibers are continuous fine fibers that have high tensile strength with high heat resistance. The pyrolytic behavior and active-passive oxidation of these fibers at high temperatures are described here. The heat resistance of these fibers increases in the order of the Si-C-O fiber, the Si-C fiber, and the SiC fiber. The high-temperature properties are dependent on the atomic arrangement and the quantity of amorphous SiC
O
and glassy carbon in the fibers.

Times Cited Count：1 Percentile：19.27(Materials Science, Ceramics)Influence of additives and hot-pressing temperature on properties of the synthetic rock was investigated, which was developed for making harmless and stabilizing fly ash from municipal waste incinerator. Sintering test at 1200
C for 16 h revealed that addition of 20 and 1.5 wt% of TiO and NaO, respectively, is necessary for preparation of dense products. X-ray diffractometry showed that these additives promoted the formation of perovskite (CaTiO
) and gehlenite (CaAlSiO
) minerals. During hot pressing, bulk density of the synthetic rock increased steeply with temperature between 1000 and 1100C. On the other hand, its open porosity decreased rapidly with temperature between 1050 and 1150C. These facts imply that the temperature of 1100
150C is practical in hot pressing of fly ash.
