Silane has poor stability and has the following characteristics.
1. Sensitive to air
Easy to self-ignite: Silane can self-ignite when in contact with air. At a certain concentration, it will react violently with oxygen and explode even at a lower temperature (such as -180℃). The flame is dark yellow when it burns. For example, during production, storage and transportation, if silane leaks and comes into contact with air, it may cause spontaneous combustion or even explosion accidents.
Easy to be oxidized: The chemical properties of silane are much more active than alkanes and are easily oxidized. Oxidation reactions will cause changes in the chemical structure of silane, thus affecting its performance and use.
2. Sensitive to water
Silane is prone to hydrolysis when in contact with water. The hydrolysis reaction will produce hydrogen and corresponding silanols and other substances, thereby changing the chemical and physical properties of silane. For example, in a humid environment, the stability of silane will be greatly affected.
3. Stability is greatly affected by temperature
Changes in temperature can have a significant impact on silane stability. Under high temperature conditions, silane is prone to decomposition, polymerization and other reactions; under low temperature conditions, the reactivity of silane will be reduced, but there may still be potential instability.
4. Active chemical properties
Silane can react chemically with many substances. For example, when it comes into contact with strong oxidants, strong bases, halogens, etc., it will undergo violent chemical reactions, leading to the decomposition or deterioration of silane.
However, under certain conditions, such as being isolated from air, water and avoiding contact with other active substances, silane can remain relatively stable for a certain period of time.
