“…It can be found that the apparent porosity, water absorption, and bulk density of sample 21 are the lowest, while the flexural strength is the largest. The reason may be that the waste glass leads to the viscosity of viscous material being larger, the diffusion speed of material becomes slower, the gap between particles is not filled sufficiently, and the porosity is high [12] , which is consistent with the above results of morphological characterization of the glass-ceramic samples. However, the diffusion rate of the material is fast in sample 21, and a large number of crystalline phases are precipitated, and the glass phase is gradually transformed into feldspar and other crystalline phases.…”

To realize the utilization of andesite tailings and solve the environmental problems caused by municipal solid waste incineration (MSWI) fly ash, both of them were selectively used as raw materials to prepare glass ceramics by sintering process. The effects of components on the properties of glass ceramics were analyzed. The results showed that glass-ceramic sample 21 prepared from andesite tailings and MSWI fly ash had the best performance, the bending strength was 94.8Mpa. At the same time, its acid and alkali resistance were the best, while the thermal conductivity was the lowest. The leaching of heavy metal elements in all the samples met the Chinese national standard. These results will provide some reference for the resource utilization of andesite tailings and MSWI fly ash.

“…In addition, the fluxing action by the alkali activation from network-modifying components such as CaO may also contributes in the increase of densification of sample and promoting the growth of wollastonite crystal [10]. However, if the cullet content is further increased beyond 55 wt %, the density starts to decrease probably due to the Si sp 3 electronic configuration that forms 3-dimensional geometric silicate structure, which is considered to be apt to form viscous layer, thus more effective in retaining gases inside the ceramic matrix, which consequently reducing the viscosity and leading to a lower particle density [6,9,11,12]. From Figure 1, it also found out that the density decreases as the sintering temperature is increased.…”

Lightweight glass-ceramic from waste material consists of (x) paper ash-(80-x) cullet-20 Kaolin clay where (10 ≤ x ≤ 30 weight %) are sintered at 900°C, 1000°C and 1100°C using conventional solid-state reaction technique. The influence of composition and sintering temperature on density, crystalline phase, porosity and surface pore morphology was studied. The crystal symmetry, space group and unit cell dimensions which are executed from XRD data are analyzed using SmartLab Studio II Powder XRD software. Meanwhile, the lattice parameter, cell volume, theoretical densities and porosity were estimated by Rietveld refinement method. The results reveal that all parameters exhibit a temperature-dependent character, as the temperature is increased, the density decreases and porosity increases due to bloating effects. It is also found out that the glass-ceramic compose of 25 paper ash −55 cullet-20 Kaolin clay, sintered at 900°C exhibits an optimum characteristic of the sample density reached optimum because of vitrification between cullet glass, paper ash and kaolin clay to form liquid phase which promotes adhesion and polymerization. It is observed that the surface morphology of the sample is affected by the crystallization process during sintering.

“…[9,10] are being utilized in a wide range of applications owing to their heat resistance, chemical stability, excellent mechanical properties or electric properties, etc. On the other hand, as another type of silicon-based ceramics, silicate ceramics also have been applied as dielectric ceramics [11] and bioceramics [12,13]. A variety of studies have demonstrated the fabrication processes of silicon-based of the organosilicon polymers.…”

Polymer-derived ceramics (PDCs) strategy shows a great deal of advantages for the fabrication of advanced ceramics. Organosilicon polymers facilitate the shaping process and different silicon-based ceramics with controllable components can be fabricated by modifying organosilicon polymers or adding fillers. It is worth noting that silicate ceramics can also be fabricated from organosilicon polymers by the introduction of active fillers, which could react with the produced silica during pyrolysis. The organosilicon polymer-derived ceramics show many unique properties, which have attracted many attentions in various fields. This review summarizes the typical organosilicon polymers and the processing of organosilicon polymers to fabricate silicon-based ceramics, especially highlights the three-dimensional (3D) printing technique for shaping the organosilicon polymerderived ceramics, which makes the possibility to fabricate silicon-based ceramics with complex structure. More importantly, the recent studies on fabricating typical non-oxide and silicate ceramics derived from organosilicon polymers and their biomedical applications are highlighted.
