Summary

Recently, UV polymerization has become an attractive process for curing aqueous ceramic slurries. The curing mechanism of this process is the gelling of water soluble monomers incorporated into the slurries using UV activation. In this paper, the curing kinetics of aqueous alumina slurries with acrylamide as a monomer was investigated at various monomer, photoinitiator, and coinitiator concentrations. The effects of powder addition on polymerization rates of acrylamide solutions was also studied. The results demonstrated that a 3 mm cure thickness of the slurry can be attained in 9 seconds of UV exposure.
