This study reports the investigation of producing glass-ceramic composites from fly ash and varying quantities of beverage waste glass and magnesium oxide as main raw materials. Preparation and properties of porous SiCAl2O3 ceramics Jul 31, 2018 · In this paper, we first reported that porous SiCAl 2 O 3 ceramics were prepared from solid waste coal ash, activated carbon, and commercial SiC powder by a carbothermal reduction reaction (CRR) method under Ar atmosphere. The effects of addition amounts of SiC (0, 10, 15, and 20 wt%) on the postsintering properties of as-prepared porous SiCAl 2 O 3 ceramics, such as phase composition
Preparation and structure analysis of diopside glass-ceramic from coal fly-ash YAO Shu-yu,WANG Zong-feng,HAN Ye,ZHANG Wei-wei(School of Materials Science and Engineeing,Shandong University of Science and Technology,Qingdao 266590,China) Preparation of glass ceramic foams for thermal insulation Abstract. Glass ceramic foams were prepared by direct foaming method, using coal fly ash and waste glass as the main materials, borax and calcium carbonate as fluxing agent and foaming agent, respectively. The effects of coal fly ash additions, foaming time, heating rate and sintering temperature on the bulk density, porosity, mechanical properties and thermal conductivity were systematically Preparation of glass ceramic foams for thermal insulation Jun 01, 2016 · The optimum parameters to prepare the glass ceramic foams were obtained at 800 °C for 45 min with 40 wt.% coal fly ash, 60 wt.% waste glass, 30 wt.% borax and 0.5 wt.% calcium carbonate. The specimens prepared this way have a low bulk density (as low as 0.46 g/cm 3 ), exhibiting considerable compressive strength (exceeding 5 MPa) and low thermal conductivity (about 0.36 (W/m
