タイトルまたは説明

Nafenâ„¢ is aluminium oxide nanofibers produced from liquid melt. The fibers are synthesized in mats, coaligned. The aluminium oxide is in gamma and chi phases. Depending on process parameters, mean diameters from 7 to *0 nm are available. Fibers as long as *5 cm can be produced. Average mat density ranges from 0.1 to 0.4 g per cubic cm. The fibers can be easily dispersed in water and alcohols. Fibrous structure is maintained when heating up to ********0C, after which fibers recrystallize into alpha phase. Crystalline and surfacial structure has been studied, indicating possible areas of application: high-temperature insulation, metal and ceramic matrix composites, grain modification, ultra- and nanofiltration, catalysis, and more.
