One and the same product can often function as both the wetting and the dispersing additive. Additives will not help in step 2, the actual dispersion of

Most high alumina refractories are clay-based ceramics to which an alumina-rich mineral is added to chemically react with a majority of the silica present to promote mullite formation [7]. High alumina refractories contain a minimum of 60 wt% Al 2 O 3, although the Al 2 O 3 content can be 99% for specialty products. High alumina refrac-

pKa value of the ionizable ligand-modified nanoparticles changes with nanoparticle size and shape [29]. These structural and environmental factors affect the actual ionization of nanoparticles. Thus, the apparent pKa of nanoparticles is generally lower than the calculated pKa of the individual molecules or monomers in the nanoparticles. Glossary

This is a draft report on the safety of alumina and aluminum hydroxide as used in cosmetics. Alumina is reported to function in cosmetics as an abrasive, absorbent, anticaking agent, bulking agent, and opacifying agent; aluminum hydroxide is reported to function as a buffering agent, corrosion inhibitor, and pH adjuster (Table 1).

The solid-state sintering presents the third step in ceramics production. For alumina ceramic, solid-state sintering involves densifying a green body into a dense solid object at a high temperature above 1500-1800 C without melting (the melting point of alumina is 2050 C). Sintering to full density can be achieved at atmospheric pressure .
