Controlling ceramic porosity using carboxylate-alumoxane nanoparticles
The formation of carboxylate substituted alumina nanoparticles, [Al(O) x(OH)y(O2CR)z]n, is an environmentally benign and inexpensive process. The alumoxane nanoparticles are synthesized from the mineral boehmite with carboxylic acids. The physical characteristics of carboxylate-alumoxanes, such as …
