Calcination of Nickel Mud [PDF]
Abstract Different characterizations were carried out on uncalcinated nickel mud and samples calcined in the temperature range of 200–600 °C. In the present paper, the phase composition and structure transition of the nickel mud heated from room temperature are indicated by SEM, EDX analysis and Fourier transform infrared spectroscopy ...

Impact of calcination technology on properties of calcined clays
Calcined kaolinitic clays are known to be very reactive pozzolans, and combined with limestone can enable significant clinker substitution in cementitious systems. Thermal activation of kaolinitic clays takes place when the hydroxyl groups are removed, leading to formation of an amorphous reactive structure.

Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.
