Title:
ELECTROPHORETICALLY REDENSIFIED SIO2 MOULDED BODY, METHOD FOR THE PRODUCTION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO2002020424
Kind Code:
A8
Abstract:
The invention relates to a method for producing porous SiO2 green bodies having an extremely high green density, or porous SiO2 green bodies having an internal density gradient which is adjusted in a targeted manner. The inventive method is characterised in that a porous SiO2 green body known per se and consisting of amorphous SiO2 is redensified by electrophoretically depositing SiO2 particles in the pores of the green body.
