Haute temp\u00e9rature poudre d'alumine<\/a> utilise de l'hydroxyde d'aluminium industriel ou de l'alumine industrielle comme mati\u00e8res premi\u00e8res, et est calcin\u00e9e \u00e0 une temp\u00e9rature appropri\u00e9e pour former un produit cristallin stable d'alumine de type \u03b1 ; elle est fabriqu\u00e9e \u00e0 partir d'alumine calcin\u00e9e de type \u03b1 par broyage \u00e0 billes Poudre d'alumine.<\/p>\n

Haute temp\u00e9rature poudre d'alumine<\/a>Le produit est blanc, brillant, d'une grande puret\u00e9, avec des propri\u00e9t\u00e9s chimiques stables. Bonne isolation. La microduret\u00e9 est de 2200-2300km\/mm2. Il peut \u00eatre utilis\u00e9 comme outils abrasifs fixes et outils abrasifs appliqu\u00e9s, poudre de jet humide ou sec, meulage de haute pr\u00e9cision et production de mat\u00e9riaux r\u00e9sistants \u00e0 l'usure de haute qualit\u00e9. Il convient au traitement de l'acier tremp\u00e9, de l'acier alli\u00e9, de l'acier rapide, de l'acier \u00e0 haute r\u00e9sistance et d'autres mat\u00e9riaux pr\u00e9sentant une duret\u00e9 et une r\u00e9sistance \u00e0 la compression \u00e9lev\u00e9es. Il convient \u00e9galement au meulage et au polissage des cristaux pi\u00e9zo\u00e9lectriques, des semi-conducteurs, du silicium monocristallin, du silicium polycristallin, etc. Il peut \u00e9galement \u00eatre utilis\u00e9 comme pi\u00e8ces de catalyseur, pi\u00e8ces isolantes, c\u00e9ramiques sp\u00e9ciales et mat\u00e9riaux r\u00e9fractaires avanc\u00e9s.<\/p>\n

Utilisations : Largement utilis\u00e9 dans les mat\u00e9riaux r\u00e9fractaires \u00e0 haute teneur en aluminium, les billes r\u00e9fractaires \u00e0 haute teneur en aluminium, briques de corindon<\/a>Les c\u00e9ramiques d'alumine, les briques r\u00e9fractaires, les c\u00e9ramiques d'alumine, etc.<\/p>\n

Caract\u00e9ristiques : L'alumine haute temp\u00e9rature est sp\u00e9cialement produite pour les entreprises de mat\u00e9riaux r\u00e9fractaires. Elle pr\u00e9sente les caract\u00e9ristiques suivantes : taux de conversion \u00e9lev\u00e9, bonne fluidit\u00e9, bonne dispersion et taille de particule uniforme.
