Calcination - an overview ScienceDirect Topics

Calcination is a process of heating a substance under controlled temperature and in a controlled environment. This process is known to improve the chroma, tinctorial strength, pigmentary texture, weather stability, light-fastness and thermal stability of pigment whereas it has adverse effect on the dispersibility of pigments.

Kiln vs flash calciner - FLSmidth

The kiln system provides the gradual heating and extended retention time (normally ~30 minutes) needed to effect the conversion on large particles. Conversely, a gas suspension calciner (GSC) is best suited for spodumene concentrate that has a PSD less than 1mm, which is common for concentrates produced via the floatation process.

Cathode Powder – The calcination process

Cathode Powder – The calcination process. The positive electrode in the battery is often referred to as the “cathode”. In the conventional lithium ion batteries, lithium cobalt oxide is used as the cathode. In the last few years, however, many alternative material systems have been developed and used.
