Abstract
A study is reported that fly-ash behaves as an excellent raw-material for synthesising hollow alumina composite. Coating of alumina onto the surface of ceno spheres was accomplished by controlled precipitation around pH-10. Dopants like Ni/Co have also been successfully tried. The resultant co-precipitated composites were then characterized using DTA, XRD,Particle size analysis and specific-gravity measurements. Calcination of co- precipitated samples at 1500°C, for 1h and haracterisation of the calcined product also discussed. The results indicate that alumina can be successfully coated on ceno-spheres.
