production of carbonate of alkali metal - earthy granules with heating and contemporary granulation

摘要

it is described a process for the production of carbonate of alkali metal - earthy, granules, in particular of barium carbonate and strontium carbonate.in the case of a binder and, if necessary, water is added and granula effect of mechanical forces, or in the form of a granulation for sovracostruzione.for example, in a reactor with contemporary rapid evaporation drying. it granula preferably in the presence of water.then we can submit the granules to a treatment at high temperature.neither in nor in granulation treatment at high temperature, the material granulantesi or granules is and contact with inorganic material refractory.
