What is Pseudo boehmite？
What is the best available pseudo boehmite?
What is Pseudo boehmite? Xiangrun’s alumina and boehmite have high chemical purity and dispersibility. The Important properties is pore volume, particle size and specific surface area could be adjusted. Due to their variability of properties, these aluminas and boehmites have over more than 15 years found their way into a broad range of different applications, including catalyst supports, coatings, polymer additives, paint detackifier, sol-gel abrasives and ceramics.
The structural characteristics of γ-Al2O3 and its precursor is pseudoboehmite. The pore size distribution of γ – Al2O3 converted from pseudoboehmites upon calcination at above 300℃.
Type of pseudo boehmite:
Normal pseudoboehmite
Soda Pseudoboehmite
Macroporous Pseudoboehmite
