A Study on the Utilization of Coal Fly Ash Derived Grog in

Grog is an additive material that plays important roles in ceramic making. It improves the fabrication process of green bodies as well as the physical properties of fired bodies. Few low-cost materials and wastes have found their application as grog in recent years, thus encouraging the replacement of commercial grogs with cost-saving materials. Coal fly ash, a combustion waste produced by

material and its heat-treated materials to immobilize the Cs+ in the decomposed zeolite. 2. Experimental 2.1. Preparation of mordenite The mordenite was artificially synthesized using a com-bination of rice husk ash and coal fly ash without the addition of a template agent and a seed powder (Sample (a)). The rice husk ash was obtained by Glass - Ceramics :Glass - Ceramics from Waste MaterialsJun 11, 2002 · Coal Ash Based Glass-Ceramics produced by the Petrurgic Process Figure 1 shows the typical microstructure of a glass-ceramic obtained by the petrurgic method, which was produced from a melt containing 60wt% soda-lime glass and 40wt% coal ash at a cooling rate of 10°C per minute.

In a related study, Chang et al. used red mud to produce imitation basalt fiber and investigated the effects of crystallization and iron oxide on

Microstructure and properties of mullite-based porous

Jul 11, 2016 · Using coal fly ash slurry samples supplemented with different amounts of Al 2 O 3, we fabricated mullite-based porous ceramics via a dipping-polymer-replica approach, which is a popular method suitable for industrial application.The microstructure, phase composition, and compressive strength of the sintered samples were investigated. Nucleation and Crystallization of Glass-Ceramics from Coal The nucleation and crystallization kinetics of glass obtained by melting coal fly ash with additives at 1550°C have been investigated. The optimum heat treatment schedule for the glass was nucleation at 825°C for 60min before crystallization at 962°C for 4h. The activation energy for crystallization of the glass-ceramics, obtained by the DDTA result, was 280.03 kJ/mol, lower than that of

Preparation and characterization of cordierite ceramic

Jan 13, 2019 · Coal series kaolin (CSK) is used as the raw material to prepare CSK cordierite electronic ceramics. Sintering process is analyzed by a heating microscope. The microstructure of green body, phase transformation, and microstructure evolution during sintering process is elucidated by scanning electron microscope (SEM) and X-ray diffraction (XRD). Comprehensive evaluations of our product Preparation and characterization of glass-ceramic Oct 01, 2019 · Production of glass-ceramic composites through fly ash devitrification has gradually become one of the applications being examined internationally. 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 asprepared porous SiCAl 2 O 3 ceramics, such as phase composition 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

The optimum parameters to prepare the glass ceramic foams were obtained at 800 degrees 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 K)). Preparation of high strength and low-cost glass ceramic Aug 01, 2018 · The success of recycling the molten blast furnace slagto glass fiber in industrial scale greatly encourage us to keep on seeking more environmental friendly applications from industrial waste. In this work, high strength and low-cost glass ceramic foams are prepared with extremely high coal fly ash content. The prepared glass ceramic foam sample introduced 89 % coal fly ash and 6 %
