Abstract:
(EN) The present invention relates to a method for producing a metal oxide-silica composite aerogel and to a superbly lightweight metal oxide-silica composite aerogel produced according to same and, more specifically, to a method for producing a metal oxide-silica composite aerogel, comprising the steps of: preparing an acidic water glass solution by adding an acid catalyst to a first water glass solution (step 1); producing a precursor solution by adding a metal ion solution to the acidic water glass solution (step 2); and adding a second water glass solution to the precursor solution and subjecting same to a gelling reaction (step 3).
(FR) La présente invention concerne un procédé de production d'un aérogel de composite d'oxyde métallique-silice et un aérogel extraordinairement léger de composite d'oxyde métallique-silice produit par celui-ci et, plus spécifiquement, un procédé de production d'un aérogel de composite d'oxyde métallique-silice, comprenant les étapes consistant à : préparer une solution acide de silicate de sodium par ajout d'un catalyseur acide à une première solution de silicate de sodium (étape1) ; produire une solution de précurseur par ajout d'une solution d'ions métalliques à la solution acide de silicate de sodium (étape 2) ; et ajouter une seconde solution de silicate de sodium à la solution de précurseur et soumettre celle-ci à une réaction de gélification (étape 3).
(KO) 본 발명은 산화금속-실리카 복합 에어로겔 제조방법 및 이에 따라 제조된 경량성이 우수한 산화금속-실리카 복합 에어로겔에 관한 발명으로 보다 상세하게는 제1 물유리 용액에 산촉매를 첨가하여 산성 물유리 용액을 준비하는 단계(단계 1); 상기 산성 물유리 용액에 금속이온 용액을 첨가하여 전구체 용액을 제조하는 단계(단계 2); 상기 전구체 용액에 제2 물유리 용액을 첨가하고 겔화 반응시키는 단계(단계 3)를 포함하는 산화금속-실리카 복합 에어로겔의 제조방법에 관한 것이다.
