DOI: 10.1016/j.ceramint.2019.06.012
Abstract: Abstract Cost-effective porous alumina-mullite ceramic membrane supports were prepared from mixtures of different alumina/silica (Al2O3/SiO2) ratios of coarse α-alumina micro-powder and colloidal silica (CS). The effects of sintering temperature, Al2O3/SiO2 ratio and cornstarch content on… read more here.

DOI: 10.3390/membranes10050093
Abstract: Porous ceramic membranes for aqueous microfiltration and ultrafiltration processes suffer from the high-costs of material and processing. The latter is mainly due to the high-temperature sintering step. In this work, cement-based membrane supports from ultrafine… read more here.
