The bauxite is produced with high-quality bauxite ore , which is classified, homogenized,and sintered in high temperature. It has the features of homogenized components, highbulk density, good performance in high temperature and stable quality. There is no needto classify this material when it is used. Therefore it has the quality of low cost and highperformance. It also can replace brown corundum in production.TechnicalTechnicalTechnicalTechnical datadatadatadata ofofofof BauxiteBauxiteBauxiteBauxite
