The beltlike geometrical morphology is a common structural characteristic for functional oxides with different crystallographic structures, at least for the ones we studied. For example, single crystalline SnO 2 nanobelts of rutile structure can consistently be synthesized by thermal evaporation of either SnO 2 powders (purity: 99.9%; melting point: 1630 C) at 1350 C or SnO powders (purity: 99

Hot Pressed Silicon Carbide is a high density, high strength material which has been used in refractory appliions for many years. It is now used for a wide range of engineering appliions. Silicon Carbide can be highly polished and has potential for space-based mirrors, because of its high specific strength and stiffness compared with those of glass.
