The process of calcining.


Etymology: L, calcinare, to burn lime
the heating of inorganic materials to drive off water. It is used in dentistry to manufacture plaster and stone from gypsum. Compare calcification.


The process of heating a solid (e.g., an ore) in air below its melting point to effect thermal decomposition, phase transition or remove volatiles, thereby changing the original solid into something else—e.g., heating calcium carbonate to release CO2 gas and form calcium oxide.

calcination (kal´sinā´shən),

n a process of removing water by heat; used in the manufacture of plaster and stone from gypsum.

The present study also reported the effect of high calcinations rates on the crystallinity and morphological features of the test material.
The calcinations of waste paper sludge with 600 degC temperature with 3 hours duration demonstrated the peak with maximum number of counts of silica content as illustrated in figure 3.
After calcinations Kankar lime was ground in power-driven mortar mill, fixed on the roof of a cabin.
From FE-SEM images can notice the grains size increased with calcination temperature increased and after the necklace-like crystallized nanofibers formed.
As seen from Figure 2(b), the typical adsorption peaks of PMMA were weakened, which further demonstrated that PMMA template was mostly removed from the composite microspheres by means of calcination.
In addition to the initial penalizing minerals (muscovite, quartz and feldspars) presented in the kaolin, the presence of kaolinite that has not been fully calcinated (metakaolinized) was identified in the MK-750 metakaolin, due to the calcination at the lowest temperature (750[degrees]C).
This can be achieved by an additional calcination step; however, at the calcination temperature, small particles are sintered simultaneously into hard aggregates of 1000 nm and more, (117, 118) if not already sintered during the hardly controllable combustion.
the counter effects of synthesis parameters, including hexane additive, hydrothermal temperature, synthesis temperature and calcination method has also been studied on the structure and final performance of the product.
8 tonnes of CO2, roughly 40 per cent of which stems from the combustion of fuels used to produce clinker, 10 per cent of which stems from the transport of fuel and raw materials, with the remainder coming from the calcination of limestone in kilns.
First deputy governor of the region Duisenbai Turganov said 12 new productions include greenhouse production, production of agents of fusion for the metallurgical sector, production of cooper, refinery coke calcination plant, enriching factory in Ayak-Kodzhan field, production of disinfectants and others.
