The Calcination

Calcination is used for temperatures over 300°C up to a thousand degrees Celsius. Materials undergo thermochemical transformation with the aim of changing their physical and/or chemical properties (sintering, thermal desorption, dehydration, decarbonisation, etc.).

CTP has a range of ovens from laboratory scale to pilot scale.
