Silice<\/h1>\n
\n SiO\u2082<\/span>\n <\/div>\n

CarboCore fournit de la silice pour le verre, la c\u00e9ramique, la fonderie, la construction et la filtration.<\/p>\n

La silice commence par la g\u00e9ologie, mais sa valeur se prouve en production. La silice \u00e9gyptienne provient de gr\u00e8s blancs riches en quartz et de quartzites du Sina\u00ef et du d\u00e9sert Oriental, form\u00e9s \u00e0 partir de sables d\u00e9pos\u00e9s par d\u2019anciens fleuves et rivages. L\u2019origine seule ne d\u00e9termine pas la performance. Ce sont la puret\u00e9, la teneur en fer et la granulom\u00e9trie qui comptent. C\u2019est de l\u00e0 que part chaque commande CarboCore.<\/p>\n \n
