Aluminum Oxide Nanofiber Materials

Al2O3, aluminum oxide, alumina

A valuable material for its refractory, insulating, and chemical resistance properties, aluminum oxide is also an excellent catalyst support.

Aluminum oxide (Al2O3), or more commonly referred to as alumina, is available in various crystalline structures depending on the operational conditions in which it is formed or available in an amorphous state. Alumina is a hard durable material that can be used as an abrasive, is a good electrical insulator (dielectric), has relatively high thermal conductivity, can be used as a catalyst or as a catalyst carrier, is chemically inert, and exhibits good thermal stability. MemPro’s aluminum oxide nanofibers are manufactured with a proprietary process that produces consistent fiber diameter distributions (ave. 90 – 120 nm).
