Through ball milling, pressing, sintering, the ceramic materials are prepared with different chemical compositions of mullite powders purified from the fly ash. This paper studies the influences of the sintering temperature and the composition of the microcrystalline mullite ceramics on the body shrinkage, the ignition loss, the apparent density, the impact toughness, the Vickers microhardness and the microstructure of the prepared ceramics. It is shown that with sintering mullite at 1450℃the obtained ceramic material has the most dense body shrinkage, the maximum Vickers microhardness; the sample prepared from the S type samples has an even greater density and the optimum overall performance; but the S-type sample has a large calcium oxide content and is not conducive to the impact toughness of the mullite ceramic materials., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=m9PhjvPh8P/NSQ3J+WDOzg==, pdfFileSize=3350220, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
