Hydrate nodular

Nodular hydrates up to 5 cm in diameter may occur, such as found in the Green Canyon Gulf of Mexico the gas in these hydrates may be of thermogenic origin that migrated from depth. 

The azihydrous compound forms reddish-violet, crystalline platee, very deliquescent. The hydrates form yellow, nodular, imperfectly cryst ne masses, or rhombic plates, very soluble in H,0, soluble in alcohol and ether. In solution it is convex d into FeCl, by reducing agents. The Liq, ferri chloridi U. S.) Liq, fer. perchloridi (Br.) is an aqueous solution of this compound, containing excess of acid. The l incL fer. chlor. (U. 

Yttrium is also a deoxidizer of vanadium, and its addition improves the ductility of nodular cast iron. Yttrium oxides increase the resistance of ceramic materials to heating due to an increase in melting temperature. Yttrium hydrate is used as temperature stabilizer both to increase the stability of heating alloys and to moderate neutrons in nuclear reactors (Luckey and Venugopal 1978 Greinacher 1981 Jezowska-Trzebia-towska et al. 1990).
