Mesoporous Alumina
Very-high-surface-area alumina for ceramic additive evaluation, interfacial-material studies, slurry and binder interaction studies, and porous coating-material evaluation.
Product Details
Qualification note: High BET and oil absorption can strongly affect binder demand and slurry rheology; validate in the intended formulation.
