="ChDivSummary">Biphasic calcium phosphate(BCP) nanopowders were synthesized by using microwave and non-microwave irradiation assisted processes.The synthesized powders were pressed under a pressure of 90... MPa and 2 GPa,respectively.XRD patterns of the microwave irradiation assisted and non-microwave irradiation assisted nanopowders showed the coexistence of hydroxyapatite(HA) and tricalcium phosphate......
nanopowders as raw materials and to study its properties.The MgF2 nanopowders were prepared using chemical precipitation and the translucent ceramics were fabricated by hot-pressing sintering......
indicated that nanopowders calcined at 1100 oC for 4 h were 40-70 nm in size with spherical morphology,the powder had the strongest emission peak centered at 1078 nm,corresponding to the transition......
region slightly decreased and transmission rate in visible light region was somewhat enhanced. In comparison with the silica-coated CeO2 nanopowders, the silica-coated Ce0.95Ti0.05O2 nanopowders......
Characteristics and Photoeatalytie Effects of Zn/ZnO Nanowhiskers Compared with ZnO Nanoparticles刘宏芳摘 要:<正>ZnO nanopowders were prepared by oxidizing Zn vapor in the atmosphere of mixture gas of Ar and O2 at low pressure.Tetrapod nanowhiskers synthesized at a pressure of 1.6 kPa show pure ZnO feet and Zn phase in the core of the nanopowder.The......
obviously but the chroma change was small. Pure zirconia nanopowders sintered densely could obtain the relatively high transmittance, while the transmittance and the lightness of slight addition changed......
diagram of DC plasma device for preparing refractory metal nanopowders[9] 2 难熔金属粉的热等离子体球化 射频等离子体法是球化难熔金属粉的一种高效手段[16].该方法通常选用无规则形状的难熔金属粉作为原料,通过载气将其注入等离子体炬中；经过熔化-凝固-淬火等过程后,最终制备出粒径小于原料粉末的球形难熔金属粉.与直流电弧等离子... nanopowders by plasma arc evaporation[J].
