- 摘要：
The present invention concerns pelletized materials for use in chemical conversion processes in industry or agriculture, in which alkaline compounds in powder form are pelletized with hydroxides of substances having highly different solubility products in a manner such that initially in a first stage with the addition of small quantity of pelletizing water nuclei of a size of 0.05 to 0.15 mm are formed and that subsequently the nuclei formed are combined into pellets by the addition of more pelletizing water, and a process for their preparation. To the initial material in the first stage a quantity of pelletizing water sufficient for hydrating, but not substantially exceeding said quantity, is added and following the onset of nucleation the further addition of water is interrupted until the initial materials are completely hydrated. The pelleting water required for the continuation of nucleation is added only after said hydration. For the preparation of pellets for the elimination of nitrogen impurities an
