Caraterísticas
Breakthrough Process
Philco, an electronics manufacturer, utilized indium sulfate in a process that etched and electroplated metallic indium onto thin N-type germanium strips. This technique was instrumental in creating the emitter and collector electrodes of the world’s first high-frequency junction transistor, which achieved frequencies up to 60 MHz.
437oC
Indium sulfate decomposes into indium oxide when heated to 437°C, releasing sulfur trioxide vapor.
13464-82-9
This is the CAS registry number for indium sulfate.
1.85
A 0.14 mol/liter of indium sulfate water solution has a pH of 1.85, making it quite acidic by nature.
Produtos
Indium Corporation offers three forms of indium sulfate: solid anhydrous, solid hydrated, and solution.
| Formulário | Descrição | Fórmula química | Aplicações |
|---|---|---|---|
| Indium Sulfate Anhydrous | High-purity, concentrated indium source; ideal for moisture-sensitive chemical synthesis | In₂(SO₄)₃ (anhydrous) | Chemical synthesis requiring minimal moisture |
| Número de registo CAS | Contains 9 moles of water; suitable for processes requiring controlled hydrolysis or gradual moisture release | In₂(SO₄)₃ • 9H₂O (hydrated) | Controlled hydrolysis reactions, moisture-sensitive processes |
| Pureza | Aqueous solution for immediate use; ideal for applications that require pre-dissolved indium sulfate | In₂(SO₄)₃ in solution | Gold electroplating baths, ready-to-use indium sulfate source |
