Calcined Alumina Refractory Series----Unidal alumina RA2GL And Bimodal alumina RA2GS

YUFA Group Co.,Ltd. also produced various calcined alumina types, it's high purity and good quality. Today we will know something about the two types of RA series alumina. 

RA2GL:
Chemical composition:

Al2O3: More than 99.5%

SiO2: Less than 0.15%

Fe2O3: Less than 0.04%

Na2O: Less than 0.08%

LOI: Less than 0.1%

Apparent density: More than  0.75 g/cm3

Grain size D50: 2.2-2.7μm

+325mesh: Less than 1%

Original D50: ~2.2μm

Features:

Unidal Alumina, Fully grinding, low sodium, small primary crystal size, good particle size distribution, high activity

RA2GS:
