“…This may be achieved by adopting fast firing cycles and using fluxes. Many studies on the use of fluxing agents in the production of ceramic products for reducing the firing temperature have been reported [6][7][8][9][10]. For the firing cycle, there is also much literature on the effect of temperature and soaking time on the ceramic properties [11][12][13][14].…”

Four mixtures of kaolinite clay and feldspar (Western-Cameroon) were prepared and sintered at 1200 • C for 2 h at the heating rate of 5 • C/min, 10 • C/min, 15 • C/min and 20 • C/min. The main new crystalline phase was mullite associated with quartz, anatase and cristobalite for all heating rates. By increasing the feldspar content, both the amounts of mullite and of glassy phase increase which promotes the densification of the samples. Heating rate has less influence on the formation of new mineral phases, while this process is sensitive to flux content. Both heating rate and flux content have an effect on the microstructure of the fired bodies as well as technological properties. The specimens with 30% feldspar content sintered at 1200 • C from 5 • C/min to 20 • C/min exhibited water absorption values <10% and bending strength >12 MPa. These materials are suitable as wall tiles. Thus, these samples can be sintered at a heating rate of 20 • C/min instead of 5 • C/min which leads to a saving in firing time and in energy.

The 96 reservoirs in Taiwan have a total reservoir capacity of 2.862 billion cubic meters, and a deposition rate of 28.95%. Although the reservoir sediment has similar main constituents to traditional Taiwanese glaze, it cannot independently replace Taiwanese glaze. The reservoir sediment is used as the main raw material to improve the settleability and viscosity of the reservoir sediment glaze by adjusting the proportions of raw materials, adding adhesion aid (Taiwan red clay), and the suspending agent (bentonite). The surface characteristics of the glaze are improved by finding the optimum soaking time. The recycled glass powder is blended to reduce the firing temperature of the reservoir sludge glaze. Experimental results indicate that red clay and bentonite enhance the consistency of reservoir sediment glaze paste, while sodium silicate and American fairy water reduce it. Prolonging the soaking time improves the glaze thickness. The roughness of the reservoir sediment glaze is reduced after firing, and the firing temperature is negatively correlated with the roughness of reservoir sediment glaze. The glass powder (5–10%) can reduce the firing temperature of reservoir sediment glaze by 100–150°C, but does not decrease the roughness. Therefore, this investigation recommends the optimum liquid–solid ratio (L/S) of reservoir sediment glaze paste as 1.7–1.8, the optimum blending ratio of red clay as 10–15%, the optimum blending ratio of bentonite as 5%, and the soaking time as 8 s.
