摘要
通常硅烷与氧很难共存,人们也决不会贸然在硅烷气体中作掺氧试验。一次偶然的机会,我们做配制SiH4与N2二元混合气的实验,事后发现所用N2中含氧量为4 2%(体积分数)。由此我们知道这种处于亚稳状态的硅烷混合气其潜在的危险非常之大。
Silane is pyrophoric and acutely active with oxygen.However,coexistence of silane with low content oxygen is possible.To clarify ignition behavior of silane:nitrogen mixture,an explosion case was investigated.It is found that the explosion severity of the metastable mixture with lean oxygen is extremely high.
