Manufacture of cordierite foams by direct foaming
Silva, Elisabete Ribeiro; Correia, N.; Silva, J. M.; Oliveira, F. A. Costa; Ribeiro, F. R. M. C.; Bordalo, J. C.; Ribeiro, M. F.Open cell cordiereti fosms were prepared by a direct foaming two-component polyurethane (PUR)/ceramic system. Throught optimization of several experimental parameters such as contents of catalysts and ceramic cordiereti precursor, as well as plasticizer presence, foams with porosites 85-95&% and densities ranging from 130-410 kg/m3 were obtained. Thse foams characteristics make them attractive to be used as cat...
