摘要:
The invention relates to soluble metal oxides and mixed metal oxides and to solutions comprising metal oxides and mixed metal oxides. The invention further relates to a process for preparing a soluble metal oxide and a soluble mixed metal oxide and additionally relates to a process for modifying the solubility of a soluble metal oxide. The metal oxides, mixed metal oxides and solutions thereof have a number of applications and in particular are suitable for use as catalysts and also as precursors for the formation of metal films.
摘要:
Methods of preparing stannous oxide including neutralizing a solution of divalent tin ions in a mineral acid using a weak base, followed by heating the neutralized solution optionally under an inert atmosphere are provided. The stannous oxide particles produced are readily soluble in alkyl sulfonic acids.

摘要:
Disclosed are processes for the selective extraction of tin from aqueous acidic solutions bearing tin and other metal cations. Branched tertiary phosphine oxides comprising at least two branches per alkyl group show higher extraction coefficients, E, for tin than other metals, e.g. zinc (III), iron (II), iron (III), copper (II) and lead (II). Novel compositions for selectively extracting tin comprising combinations of symmetrical branched phosphine oxides and unsymmetrical phosphine oxides are also disclosed.
摘要:
An indium tin oxide sol composition comprising about 0.5 to about 30% by weight of indium oxide, tin oxide in an amount of about 0.5 to about 30% by weight, as converted to a basis of tin, based on indium in the indium oxide, and a dispersing agent, which sol composition is obtained by contacting a solution of an indium salt of an inorganic acid containing a tin salt of an inorganic acid with an ion-exchange resin is disclosed. The indium tin oxide sol composition has a high purity and forms an excellent transparent conductive film.
