Features: This book is a specialized academic work introducing the key process affecting the quality and output of alumina plants—sodium aluminate solution crystal seed decomposition. The book is divided into 8 chapters. First, it provides an overview of the domestic and international alumina industry status, points out the problems in China's alumina industry, and explores the development direction of China's alumina industry. Next, it elaborates in detail on the structure of sodium aluminate solution, discusses the influence patterns of different decomposition conditions on agglomeration, crystal growth, and secondary nucleation, and investigates the effects of various decomposition conditions on the decomposition rate of the solution, as well as the particle size and strength of the product. By analyzing a large amount of experimental data and SEM images, the mechanisms are discussed separately. Finally, it conducts an in-depth study on agglomeration and growth kinetics, identifies the control steps, proposes corresponding enhancement measures, and explores the application of active seeds and additives as effective methods for intensifying the decomposition of sodium aluminate solution. This book is suitable for professionals in the alumina field.
