Abstract
- Sr(OH)<subscript>2</subscript> is an indispensable strontium compound extensively harnessed in sugar refining, strontium lubricating wax formulation, and polymer plastic stabilization. Sr(OH)<subscript>2</subscript>·8H<subscript>2</subscript>O is the prevalent hydrate form of Sr(OH)<subscript>2</subscript>. Deprived of moisture via vacuum drying, Sr(OH)<subscript>2</subscript> can be procured from Sr(OH)<subscript>2</subscript>·8H<subscript>2</subscript>O. Sr(OH)<subscript>2</subscript>·8H<subscript>2</subscript>O particles with larger sizes exhibit impressive attributes such as facile solid–liquid divergence, elevated product purity, expedient drying, and resilience to agglomeration, which have garnered significant interest. Given the superior quality of the product and the dependability of the process, process analytical technology (PAT) has been extensively employed in the pharmaceutical sector, rendering it feasible to employ PAT to fabricate large-particle Sr(OH)<subscript>2</subscript>·8H<subscript>2</subscript>O crystals. This study utilizes industrial SrCO<subscript>3</subscript> to prepare high-purity Sr(OH)<subscript>2</subscript>·8H<subscript>2</subscript>O with a purity of over 99.5%. The growth process of single crystals was observed using a hot-stage microscope, and the growth process of large-particle Sr(OH)<subscript>2</subscript>·8H<subscript>2</subscript>O was optimized and regulated online using PAT. The optimal process conditions were optimized, and large-particle Sr(OH)<subscript>2</subscript>·8H<subscript>2</subscript>O crystals were obtained by adding crystal seeds. On this basis, we proposed a seed control mechanism for Sr(OH)<subscript>2</subscript>·8H<subscript>2</subscript>O. [ABSTRACT FROM AUTHOR]
