C\u00e9ramique de cordi\u00e9rite<\/strong> peuvent \u00eatre produits \u00e0 l'aide de diverses m\u00e9thodes telles que la r\u00e9action \u00e0 l'\u00e9tat solide, le proc\u00e9d\u00e9 de coul\u00e9e en bande aqueuse et le frittage \u00e0 haute temp\u00e9rature.<\/p>\n Les coul\u00e9e en bande aqueuse<\/strong> Le processus implique l'utilisation de polyalcool de vinyle (PVA) et poly\u00e9thyl\u00e8neglycol (PEG)<\/strong> comme liant et plastifiant, respectivement. Avant de commencer les \u00e9tudes de coulage sur bande, une quantit\u00e9 optimale de tripolyphosphate de sodium (STPP) a \u00e9t\u00e9 utilis\u00e9e par la m\u00e9thode de s\u00e9dimentation pour disperser les poudres.<\/p>\n Les r\u00e9action \u00e0 l'\u00e9tat solide<\/strong> est la m\u00e9thode la plus couramment utilis\u00e9e pour produire de la cordi\u00e9rite \u00e0 haute temp\u00e9rature \u00e0 partir de mat\u00e9riaux de d\u00e9part comprenant du MgO, de l'Al2O3 et du SiO2 conform\u00e9ment \u00e0 la composition st\u0153chiom\u00e9trique de la cordi\u00e9rite. Des vitroc\u00e9ramiques \u00e0 base de cordi\u00e9rite ont \u00e9galement \u00e9t\u00e9 synth\u00e9tis\u00e9es \u00e0 partir de r\u00e9sidus aurif\u00e8res.<\/p>\n Les c\u00e9ramiques de cordi\u00e9rite pr\u00e9sentent quelques inconv\u00e9nients en termes de performances. L'un des inconv\u00e9nients est que les c\u00e9ramiques de cordi\u00e9rite sont fragiles et se cassent facilement<\/strong>. Un autre inconv\u00e9nient est que les c\u00e9ramiques de cordi\u00e9rite sont difficile \u00e0 usiner<\/strong> parce qu'ils sont tr\u00e8s durs.<\/p>\n Cependant, de nombreuses \u00e9tudes visent \u00e0 am\u00e9liorer les propri\u00e9t\u00e9s des c\u00e9ramiques de cordi\u00e9rite en ajoutant diff\u00e9rents mat\u00e9riaux ou en modifiant le processus de production.<\/p>\n
