Calcination - Wikipedia

Calcination is one of the most common processes used in the ceramics industry among many others. The most common application for Calcining is the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement. The product of calcination is usually referred to as "calcine," regardless of the actual minerals undergoing thermal treatment.

Sintering - Wikipedia

The temperature difference between this stage and the decomposition stage is large, so the material has a strong luminescence. The temperature of this stage is ℃. Sintering: it is also known as lime absorption. The tricalcium silicate is produced at this stage and the temperature in cement kiln is up to ℃.

Calcination | chemical process | Britannica

with calcination temperature (see Figure 5). At 600 oC (Figure 5a) it is obvious that the CCTO formation not completed and there is no dense microstructure. However, there is only a small difference between microstructure for samples calcined at 700 oC and 800 oC (Figure 5a & 5b). Therefore, both samples gave almost similar dielectric constant.
