原始语种摘要: The production of low cost ceramic membranes has been studied by many researchers using a variety of natural raw materials such as clays, kaolins, limestones, dolomites, zeolites, diatomites and various kinds of wastes such as fly ash, sawdust, sewage sludge, bagasse, waste glass, ceramic scrap, etc., modifying the membranes microstructure with the aim to improve their surface porosity, pore size, pore distribution and mechanical strength. Compositions of ceramic membranes containing halloysite clay, limestone and waste diatomite from the brewery industry are prepared. The change of the ceramic membranes properties varying the presence of halloysite clay and diatomite is followed. The ceramic membranes studied are prepared by dry pressing at 50 MPa and sintering at 1100°C within 2 h. The...
