Patent number: 5872070Abstract: The present invention provides for amorphous, nanoporous, ceramic material having a surface area in excess of 70 m.sup.2 /gm and characterized by a high content of open microporous cell structure wherein the micropores have a mean width of less than 20 Angstroms and wherein said microporous structure comprises a volume of greater than about 0.03 cm.sup.3 /gm of the ceramic. The invention also provides a process for the preparation of such nanoporous ceramics wherein a ceramic precursor polymer or oligomer is gradually heated in the presence of an inert gas or vacuum up to a maximum temperature in the range of greater than 400.degree. C. up to about 650.degree. C. Optionally, the process may also include a crosslinking step conducted prior to the heating step wherein the precursor polymer or oligomer is heated in the presence of a crosslinking agent capable of undergoing addition or substitution reactions with backbone atoms present in said precursor material, at an intermediate temperature of about 100.Type: GrantFiled: January 3, 1997Date of Patent: February 16, 1999Assignee: Exxon Research and Engineering CompanyInventors: John Pickett Dismukes, Jack Wayne Johnson, James L. Pizzulli
