| Questions And Answer | Back Directory | [Uses]
Trisilane is a flammable and toxic liquid at room temperature and pressure. Its main uses are in the manufacture of semiconductor silicon films and amorphous silicon. | [Properties]
Colorless liquid; density 0.743 g/mL at 0°C; freezes at –117.4°C; boils at 52.9°C; vapor density 4.15 g/L at atmospheric pressure; decomposes in water; decomposes in carbon tetrachloride.
| [Description]
Silicon forms a series of hydrides known as silanes, formula SinH2n+2, where n is the number of silicon atoms in the molecule. This general formula for the silicon hydrides is similar to the CnH2n+2 for the alkane class of hydrocarbons.
