Inorganic oxide aerogel microbeads of narrow pore diameter distribution and the method for their preparation |
摘要 |
Microbeads of aerogels of one or more oxides are characterised by a high porosity and the fact that at least 90% of the pores present have a diameter lying within a very narrow range. The surface area exceeds 300 m2/g and more frequently exceeds 500 m2/g, the total pore volume exceeding 1 ml/g.
