Silane (Silicane) is an inorganic compound with chemical formula SiH 4. It is a colorless, pyrophoric gas with a sharp, repulsive, pungent smell, somewhat similar to that of acetic acid. [6] Silane is of practical interest as a precursor to elemental silicon.

Mar 5, 2025 · Despite its importance in various industries, silane poses significant health risks. It is a colorless, flammable, and poisonous gas. Inhalation of silane can cause respiratory irritation, difficulty breathing, and damage to internal organs upon repeated or prolonged exposure.

Additional guidance on operational steps associated with the use of silane and silane mixtures as well as fire protection, gas moni-toring, ventilation, and related safeguards are provided. The requirements of the standard apply to pure silane and silane mixtures with a …

At normal temperature and pressure, silane is a colorless gas. It is a pyrophoric gas, which means that it undergoes spontaneous combustion in air. Above 788°F (420°C/693.15 K), silane breaks down into silicon and hydrogen. In electronics, it is often used as an active gas enabling silicon depositions and for solar panels manufacturing.

Nov 5, 2024 · It is also known as silicon hydride (IV), silicon tetrahydride, or monosilane. Furthermore, silane is a pyrophoric gas, which means it can spontaneously ignite at temperatures below 130°F, causing burns and fires. Due to its flammability, the production of silane gas requires strict safety measures.

Silane is a colorless, flammable and poisonous gas, with a strong repulsive odor. It is easily ignited in air, reacts with oxidizing agents, is very toxic by inhalation, and is a strong irritant to skin, eyes and mucous membranes.

Silane does not mix easily, rather, it has the tendency to form pockets in another gas. This is significant because if mixing is not complete a pyrophoric concentration may exist locally and a spark could cause a fire or explosion.

The use of the pyrophoric gas silane as a source of silicon has grown with its consumption by semiconductor manufacturers, producers of solar cells, and allied technologies. Systems once imagined to be rare are now commonplace and are in use worldwide.

Jan 1, 2021 · Silane (SiH 4) is a group 14 hydride, flammable and colorless gas with an unpleasant smell of vinegar (acetic acid). The presence of Si(OR) 3 and organofunctional (vinyl-, amino-, epoxy-, etc.) groups is practically responsible for its use as a precursor to elemental silicon and adhesion mechanism.

Silane is a pyrophoric gas (i.e. it may spontaneously ignite when exposed to air) commonly used in semiconductor fabrication. However, it does not always ignite immediately upon exposure to the atmosphere. Lack of instantaneous ignition can.
