Abstract
The effects of silane temperature and ambient moisture on the ignition behavior are considered. The critical velocity for delayed ignition is determined for different silane temperatures and moisture contents in ambient air. The logarithm of the critical exit velocity is found to be inversely proportional to silane temperature. It is also observed that moisture in air has a strong inhibiting effect on silane autoignition in air. From a safety perspective, it is concluded that prompt ignition of silane is favored in a high-temperature and low-humidity environment.
