Provided is a basic metal nitrate suitable as an oxidizing agent for a gas generating agent, which is a basic metal nitrate having a good thermal stability and meeting at least one requirement of the following (a) to (d):

Basic metal nitrate, process for producing the same and gas generating agent composition

The present invention provides a process for producing a gas generating agent capable of constantly producing a gas generating agent with a high quality. The process for producing a gas generating agent comprises the first step of feeding nitroguanidine, a basic copper nitrate and guar gum and stirring and mixing them in the presence of moisture, the second step of extrusion-molding and cutting the mixture, and the third step of drying it.

Gas generating compositions for air bag

A gas-generant-molded-article for air bags which is prepared by molding a gas generant composition into a cylindrical form containing an opening hole, wherein the relationship between the linear burning velocity r (mm/second) of said gas generant composition under a pressure of 70 kgf/cm and a thickness W (mm) of said molded article falls within a range represented by 0.005&lE;W/(2&middot;r)&lE;0.3, with the linear burning velocity preferably falling within a range of from 1 to 12.5 mm/second.
