“…Sample P synthesized from pure oxides has lower CTE than sample A (synthesized from minerals). As the CTE of materials is greatly dependent on the bond strength between the atoms, the existence of mixed alkali oxides in sample A will acted as a modifying oxides and might distorted some of the silicate chains, thus, decrease the rigidity of the network structure [14]. The mixed alkali oxides were expected to be interstitial inside the two structure holes or interstitial vacant sites that were present per unit formula in the c-axis of ␣-cordierite structure [15].…”

“…The study on preparing glass ceramics with industrial wastes has been made since the early 1960s, and some results were widely reported [8]. Various crystallization systems are involved, for example, the system of SiO 2 -Al 2 O 3 -CaO-MgO, SiO 2 -Al 2 O 3 -CaOFe 2 O 3 , and SiO 2 -Al 2 O 3 -CaO-Na 2 O [9][10][11][12].…”

The crystallization process of iron-rich glass-ceramics prepared from the mixture of nickel slag (NS) and blast furnace slag (BFS) with a small amount of quartz sand was investigated. A modified melting method which was more energy-saving than the traditional methods was used to control the crystallization process. The results show that the iron-rich system has much lower melting temperature, glass transition temperature (T g ), and glass crystallization temperature (T c ), which can result in a further energy-saving process. The results also show that the system has a quick but controllable crystallization process with its peak crystallization temperature at 918°C. The crystallization of augite crystals begins from the edge of the sample and invades into the whole sample. The crystallization process can be completed in a few minutes. A distinct boundary between the crystallized part and the non-crystallized part exists during the process. In the non-crystallized part showing a black colour, some sphere-shaped augite crystals already exist in the glass matrix before samples are heated to T c . In the crystallized part showing a khaki colour, a compact structure is formed by augite crystals.

“…The bonds located at 3610 and 1595 cm −1 were attributed to O—H stretching and bending vibrations, respectively. The band 1074–955 cm −1 was assigned to the asymmetric stretching vibration of Si—O—Si bond within [SiO 4 ] . The band 694–600 cm −1 belonged to Si—O—Si symmetric stretching vibration.…”

Lithium zeolites with ABW framework were synthesized from coal fly ash by hydrothermal method. The effects of LiOH·H2O concentrations, hydrothermal temperatures, and reaction time on zeolites formation were investigated. LiOH·H2O acted as a strong activator and promoted the dissolution of coal fly ash. The contents of zeolites ABW phases increased at the expense of quartz and mullite in fly ash with an increase of alkaline solution concentrations. On increasing hydrothermal temperatures and time, the soluble species recrystallized and phase transformation between different zeolites was observed. Morphology evolution revealed that the zeolites developed from radiating cluster to mono‐column. The reaction mechanisms were proposed as well. © 2012 American Institute of Chemical Engineers Environ Prog, 32: 790–796, 2013
