Abstract
A gas generating composition comprises an azide of an alkali metal or an alkaline earth metal, and manganese dioxide for oxidizing the azide. The composition further includes a clay material containing at least 37% by weight of silicon dioxide and having a mixing ratio of at least 5.5% by weight. This composition can allow burning to be conducted at low temperature to ensure the generation of the desired gas. The strength of a pellet of the composition can be improved without generating a toxic gas or reducing the burning rate or reducing the working efficiency in producing the pellet.
