Kusiyana pakati white corundum powder uye alumina powder

White corundum poda uye alumina poda ine chimiro chakafanana uye mazita akafanana. Vanhu vazhinji vanoda kujekesa musiyano uri pakati pavo. Iyo inotevera Qianjiaxin Refractories inoisiyanisa kubva kune yayo kuumbwa.

1. White corundum powder

(1) Chimiro cheCrystal: trigonal crystal system;

(2) Density: 3.90 g/cm3;

(3) Kuoma: Knoop kuoma 2000-2200Kg / mm2, Mohs kuoma 9.0;

(9) Coefficient yekuwedzera kwemutsara: (7-9)*10^-6/K(0-1600C).

2. Alumina upfu

(1) Kuonekwa: poda yakachena, crystalline phase γ chikamu;

(2) Avhareji yekukura kwechidimbu (nm): 20±5;

(3) Content %: mukuru pane 99.9%;

(4) Kunyungudika: 2010℃-2050℃;

(5) Poindi yekubikira: 2980 ℃;

(6) Hukama density (mvura = 1): 3.97-4.0;

(7) Ruvara: chena, rima rebhuruu mushure mekuverengera.

White corundum poda inogona kushandiswa sekuonana midhiya, insulators uye chaiyo yekukanda jecha, etc. Alumina poda ze inogona kushandiswa mukupisa conduction, polishing, electroplating, catalyst, nezvimwe.
