abstract={In this study, the effect of air blast furnace slag (ABFS) and ¦Ã-Alumina additions on densification, crystalline phases, microstructure, mechanical and electrical properties were investigated. ABFS was added partially in replacement of ¦Ã-Alumina and/or feldspar for preparing electro-porcelain compositions. The presence of slag from 15 up to 30 mass % to the standard mix (¦ÃAS0) which fired at 1300C for 1h led to relatively low bulk density (BD) ranging between (2.21 and 2.32 g/cm<SUP>3</SUP>) as compared with standard mix (¦ÃAS0) (BD 2.51 g/cm<SUP>3</SUP>), this may be due to presence of much high fluxing oxides in the fired bodies. The main phases recorded were anorthite, corundum, cristobalite with traces mullite The relevant of electroceramic bodies produced exhibited high values for volume resistivity (VR) (25x10<SUP>11 </SUP>to 30x10<SUP>11</SUP>¦¸/cm) and relatively low values in the dielectric strength (DS) (11 to 12.43 kv/mm ) as compared with standard mix (¦ÃAS0), (VR) (12x10<SUP>11</SUP>¦¸/cm) and (DS) (15.76 kv/mm), respectively. The present results show that it is possible application of recycled slag after grinding and elimination any iron contamination for the production of low voltage electrical insulators electro-ceramic bodies.},
