Hydrides zirconium

Hydrides. Zirconium hydride [7704-99-6] in powder form was produced by the reduction of zirconium oxide with calcium hydride in a bomb reactor. However, the workup was hazardous and many fires and explosions occurred when the calcium oxide was dissolved with hydrochloric acid to recover the hydride powder. With the ready availabiHty of zirconium metal via the KroU process, zirconium hydride can be obtained by exothermic absorption of hydrogen by pure zirconium, usually highly porous sponge. The heat of formation is 167.4 J / mol (40 kcal/mol) hydrogen absorbed. [Pg.433]

Hydrides. Zirconium hydrides react easily with unsaturated molecules. This process, termed hydrozirconation, replaces the hydrogen with the unsaturated group ... [Pg.439]

Mono(hydride) zirconium species grafted on a silica surface show a high reactivity toward alkanes. This system has been studied using modern 2D NMR techniques, such as double quantum (DQ) rotor synchronized 2D H MAS and C- H HETCOR, to investigate the mechanism of formation of a zirconium bis(hydride) species and the simultaneous generation of silicon mono- and bis(hydride) species [111]. Figure 11.4 shows the H MAS NMR spectrum and DQ rotor-synchronized... [Pg.440]
