Technology Process of hafnium dihydroxide

There total 3 articles about hafnium dihydroxide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

hafnium + urea hydrogen peroxide adduct (124-43-6) → hafnium dioxide (12055-23-1) + hafnium hydroxide (12027-05-3) + HHfO + hafnium dihydroxide (91223-89-1)

Guidance literature:

In gaseous matrix; laser-ablated Hf atoms were reacted with H2O2 molecules in excess argon during condensation onto a 10 K cesium iodide window; Andrews, L. Chem. Soc. Rev., 2004, 33, 123; detected by IR spectra;

DOI:10.1021/ic050614a

Reference yield:

hafnium + hydrogen (1333-74-0) + oxygen (80937-33-3) → hafnium dioxide (12055-23-1) + hafnium hydroxide (12027-05-3) + HHfO + hafnium dihydroxide (91223-89-1) + HfH2 (12770-26-2)

Guidance literature:

In gaseous matrix; byproducts: HfH4; other Radiation; laser-ablated Hf atoms were reacted with H2 and O2 molecules in excess argon full-arc irradiation and annealin to 24-30 K; Andrews, L. Chem. Soc. Rev., 2004, 33, 123; detected by IR spectra;

DOI:10.1021/ic050614a

Reference yield:

hafnium + hydrogen (1333-74-0) + oxygen (80937-33-3) → hafnium monoxide (12029-22-0) + hafnium hydroxide (12027-05-3) + HfH4 (64790-43-8) + hafnium dihydroxide (91223-89-1) + HfH2 (12770-26-2)

Guidance literature:

In neat (no solvent); (further products), laser ablated Hf co-deposited with H2+O2 in excess Ar onto a 10K CsI window, annealed at 24-30 K (mechanism discussed); not isolated, detected by IR;

DOI:10.1021/jp054482i
