Abstract:

Biopolymers obtained from bacterial sources were shown to be effective processing aids in the preparation of aqueous suspensions of submicron-sized ceramic powders. Potentially useful native bacterial polysaccharides was shown to be necessary to achieve suspension stability in aqueous systems. Alginates obtained from both alga and bacterial were also found to be effective processing aids. As in situ processing method was developed through the growth of alginate-producing bacterial in the presence of ceramic particles.
