  • Process for fabricating crystalline metal oxide material
    Patent number: 6168830
    Abstract: The invention relates a process for fabricating crystalline metal oxide materials comprising tin oxide, zirconia, or titania in form as powder, monolith gel or film by first forming a metal oxide material containing —OH surface group through a sol-gel process, and then treating them with [SiRm]nXzHy compound which reacts with the —OH group to form —OSiRm surface group, and heating the thus-treated oxide material at a high temperature to crystallize them into a crystalline metal oxide material with high crystallinity, small crystal size (<100 Å) and high surface area (>100 m2/g).
