Umahluko phakathi kwe-white corundum powder kunye ne-alumina powder
Umehluko phakathi umgubo omhlophe we-corundum kunye nomgubo we-alumina
I powder emhlophe ye-corundum kunye ne-alumina powder inokubonakala okufanayo kunye namagama afanayo. Abantu abaninzi bafuna ukucacisa umahluko phakathi kwabo. Ezi zilandelayo ze-Qianjiaxin Refractories ziyakuhlula kukwakheka kwayo.
1. Umgubo omhlophe we-corundum
(1) Ubume beCrystal: inkqubo yekristale engunxantathu;
(2) Ubuninzi: 3.90 g/cm3;
(3) Ubunzima: Ubunzima be-Knoop 2000-2200Kg / mm2, ubunzima be-Mohs 9.0;
(4) Indawo enyibilikayo: 2250C;
(5) Ubushushu obuphezulu bokusebenza: 1900C;
(6) Ukushisa okuthe ngqo (iCal/gC): 0.26 (20-90C);
(7) I-Thermal conductivity: 900C kwindawo yokushisa (iCal / cm3.sec.C);
(8) Isalathiso se-refractive: e=1.760 w=1.768 (Na line);
(9) I-Coefficient yokwandiswa komgca: (7-9)*10^-6/K(0-1600C).
2. Umgubo we-alumina
(1) Ukubonakala: umgubo omhlophe, isigaba se-crystalline γ;
(2) Umyinge wobungakanani bamasuntswana (nm): 20±5;
(3) Umxholo %: ngaphezulu kwama-99.9%;
(4) Indawo yokunyibilika: 2010℃-2050℃;
(5) Indawo yokubilisa: 2980 ℃;
(6) Ubuninzi bobudlelwane (amanzi = 1): 3.97-4.0;
(7) Umbala: omhlophe, luhlaza okwesibhakabhaka emva kokubala.
I-powder emhlophe ye-corundum ingasetyenziselwa njengemidiya yoqhagamshelwano, i-insulators kunye nesanti echanekileyo yokuphosa, njl njl.
