Monohydrate crystals

Sodium carbonate monohydrate crystals from the crystallizers are concentrated in hydroclones and dewatered on centrifuges to between 2 and 6% free moisture. This centrifuge cake is sent to dryers where the product is calcined 150°C to anhydrous soda ash, screened, and readied for shipment. Soda ash from this process typically has a bulk density between 0.99—1.04 g/mL with an average particle size of about 250 p.m. 

Gout A group of disorders of purine metabolism, manifested by various combinations of hyperuricemia recurrent acute inflammatory arthritis induced by crystals of monosodium urate monohydrate tophaceous deposits of monosodium urate monohydrate crystals in and around the joints of the extremities, which may lead to crippling destruction of joints and uric acid urolithiasis. 

Another reported study involved the preparation of four niclosamide solvates and the determination of the stability of the crystal forms in different suspension vehicles by DSC and TG analysis. Thermal analysis showed that the niclosamide solvates were extremely unstable in a PVP-vehicle and rapidly changed to monohydrated crystals. A suspension in propylene glycol was more stable and TG analysis showed that crystal transformation was less rapid [18].
