DEFINITION

Classification: 526/159

(under subclass 90) Subject matter wherein the specified material contains a nontransition metal in elemental form, or contains a hydride of a nontransition metal, or contains a compound of a nontransition metal wherein the nontransition metal atom is directly bonded to a carbon atom (e.g., TiCl4 and LiAlH4[end subscrpt], etc.).
