Active alumina dry gel powder

Thread Content

Are there anyone who has experience in producing activated alumina dry gel? I hope to get some guidance from my seniors. Technical specifications for 430-LD activated alumina powder:
Parameter | Value range
Pore volume, ml/g | 0.55–0.75
Specific surface area, m2/g | ≥290
Na+%, % | ≤0.05
Dry basis percentage | ≥70
Fe2O3%, % | ≤0.08
SO42-, % | ≤1.6
3H2O%, % | ≤5.0
Percentage of particles passing through a 0.09 mm sieve | ≥98
Percentage of pores with a diameter of 3–15 nm among total pores | ≥75
P2O5%, % | 1.0–2.5
