Utilization of Sugar-Beet Industry By-Products for the Production of Anorthite

摘要

The filter cake produced from the processing of juice purification during the production of sugar from sugar-beet is a solid waste, which represents a major problem unless it is utilized. Accordingly, the aim of the present work is to study the suitability of sugar-beet filter cake as a novel starting material in the preparation of anorthite bodies. To synthesize anorthite bodies, El-Tieh kaolin (Al_2O_3·SiO_2·2H_2O) from Sinai, Egypt, was used as a source of alumina and SiO_2, while the filter cake was used as a source of CaO. A predominant anorthite phase was found to be present on sintering the anorthite batches at 1200°C and up to 1350°C for 1 h. The prepared bodies possess a bending strength of 25.23 MPa and a relative density of 64.5 %.
