特點

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.

437^oC

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.
