摘要: Abstract Alumina prepared by fume pyrolysis of sols consisting fibrillar boehmite, 100 nm in length and 10 diameter, was subjected to the thermal resistant tests. Even after calcination at 1473 K for 30 h, alumina still consisted fibrils possessed a surface area as high 50 m2/g. This ascribed suppression rate phase transformation α-alumina, caused fact that particles are crude structures assembled fibrils.
