NAFEN (tm)

タイトルまたは説明

A new ceramic nanomaterial is presented, branded as Nafen™. Nafen™ powder is made from 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. The unprecedented production volume of 0.5 kg per hour on small-size pilot reactor supports huge market potential for this material.
