Large amounts of rice husk ash (RHA) are discharged from rice husk power plants, and the development of an effective system for recycling this RHA waste would be desirable. In the current study, the silica component of RHA obtained from a rice husk power plant in Myanmar was successfully used as raw material for the synthesis of the aluminosilicate nanotube (ASNT) material. The RHA used contained over 90 wt% of silica. The synthesized ASNT had a web-like structure formed of fi brous bundles, each containing many individual ASNT.
