Pseudo boehmite is widely used as a catalyst support and precursor in refining and petrochemical processes due to its high surface area and thermal stability. It is especially effective in hydrocracking and hydrotreating applications where it helps disperse active metal components like nickel, molybdenum, or cobalt. Its tunable pore structure and ability to form strong bonds with other oxides make it ideal for shaping into pellets or extrudates for industrial reactors.

In addition, pseudo boehmite serves as a key binder in catalyst formulations, improving mechanical strength and attrition resistance. It is also used in emission control systems, such as in three-way catalysts for automobiles, where it stabilizes precious metals and enhances performance under fluctuating temperature conditions.

Beyond catalysis, it functions as a filler and rheology modifier in ceramics, coatings, and polishing slurries. Its nanostructured nature allows for controlled gelation and water retention, making it valuable in advanced ceramic processing and abrasive formulations.
