Patent number: 10538461Abstract: A method includes the following steps: a) the production of a slip including more than 4% and less than 50% of ceramic particles and including: b) a first particulate fraction including of orientable particles having a median length L?50 and representing more than 1% of the ceramic particles, and c) a second particulate fraction having a median length D50 at least ten times shorter than L?50 and representing more than 1% of the ceramic particles, the first and second particulate fractions together representing more than 80% of all of the ceramic particles, in volume percentages based on the total quantity of ceramic particles; d) oriented freezing of the slip by moving a solidification front at a lower speed than the speed of encapsulation of the ceramic particles; e) elimination of the crystals of the solidified liquid phase of the block; and f) optionally sintering.Type: GrantFiled: June 11, 2014Date of Patent: January 21, 2020Assignee: SAINT-GOBAIN CENTRE DE RECHERCHES ET D'ETUDES EUROPEENInventors: Sylvain Deville, Florian Bouville, Adam Stevenson

Patent number: 10071502Abstract: Process for the manufacture of a mesoporous product comprising the following successive steps: a) preparation of a slip comprising: a solvent, an additive, more than 4%, as percentage by volume based on the slip, of a powder formed of ceramic particles, b) oriented freezing of the slip, so as to form a block comprising ice crystals separated by walls, c) removal of the ice crystals from said frozen slip block, optionally removed from the mold, so as to obtain a porous preform, d) removal of the additive, so as to obtain a preformed mesoporous product, the additive and the amount of additive being chosen so that the additive is present in a mesopore-forming micellar phase in said walls, more than 25% by volume of said ceramic particles exhibiting a size less than twice the size of the micelles of said mesopore-forming micellar phase.Type: GrantFiled: December 20, 2012Date of Patent: September 11, 2018Assignees: SAINT-GOBAIN CENTRE DE RECHERCHES ET D'ETUDES EUROPEEN, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUEInventors: Michaela Klotz, Idris Amirouche, Sylvain Deville, Christian Gilbert Guizard

Patent number: 10017427Abstract: Preparation of a slip including more than 4% and less than 50% of ceramic particles and including more than 1% of orientable ceramic particles made of a material including an oriented function, as volume percentage on the basis of the set of ceramic particles, wherein the fraction of non-orientable ceramic particles has a median length less than ten times the median length of the orientable ceramic particles if the set of ceramic particles includes less than 80%, as volume percentage, of orientable ceramic particles, oriented freezing of the slip by movement of a solidification front at a speed less than the speed of encapsulation of the ceramic particles; elimination of the crystals of solidified liquid phase of said block, optionally, sintering.Type: GrantFiled: December 6, 2013Date of Patent: July 10, 2018Assignees: SAINT-GOBAIN CENTRE DE RECHERCHES ET D'ETUDES EUROPEEN, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUEInventors: Sylvain Deville, Florian Bouville
