摘要: A method for the production of a homogenous, shaped SiO2 body of near net shape wherein amorphous SiO2 particles comprising relatively large amorphous SiO2 particles and relatively small amorphous SiO2 particles are electrophoretically deposited from an aqueous dispersion on an electrically nonconductive membrane, the shape and geometry of which correspond to the shaped SiO2 body to be produced, wherein the membrane has an average pore size which is larger than the average particle size of the smaller amorphous SiO2 particles.
