RECYCLING OF COAL FLY ASH BY CERAMIC PROCESSING

Abstract. Coal fly ash was used as raw material for the preparation of ceramic materials by a conventional powder technology route. Powder compacts were made from as-received fly ash, from calcined fly ash and from powder mixtures having 90 % of calcined fly ash plus a low-cost mineral as additive (dolomite, CaCO3.MgCO3).

Recycling of coal fly ash for fabrication of elongated

Abstract Mullite bonded SiC ceramic membranes were synthesized by a facile solid-state reaction process, using SiC, solid waste fly ash as raw materials and MoO3 as catalyst for growth of mullite at 1000 °C. The effect of MoO3 catalyst on mullitization reaction and mullite morphology was investigated. Different pore formers were used to enhance the porosity and to observe its effects on the
