a) Boehmite alumina powders, which are nano-sized in the dispersed phase, exhibit a unique combination of purity, consistency, and dispersibility that make them excellent materials for use in demanding colloidal applications. Traditionally dispersible boehmites is used in applications such as sol-gel ceramics, binder for catalysis, refractory materials, rheology control, surface frictionising and paint detackification.
b) Other more recently developed uses for these boehmite alumina powders include surface coating as well as polymer additives.
