Method for pressing oxynitride glass, disk of oxynitride glass made by said method, and pressing die for said method

The present invention provides a gas generating agent for an air bag including a fuel component of nitrogenous organic compound and an oxidizing agent as its major components, to which at least one metal nitride or metal carbide that is allowed to react with a metallic component contained in the fuel component or the oxidizing agent to form slag is added, thus providing the effects of: solving the slag collecting problem which stands in the way of commercially practicing the nitrogenous organic compound base fuels; promoting the size reduction of the gas generator through the full use of high rate of gasification of the nitrogenous organic compound base fuels; and providing a gas generating agent molded member which is strong and stable with age by improving heat resistant properties and formability of the nitrogenous organic compound base fuels which are poor compared with the metallic compound azide of an inorganic matter.

Gas-generating agent for air bag

Oxynitride glass whose composition is represented by Al&mdash;Si&mdash;O&mdash;N or M&mdash;Al&mdash;Si&mdash;O&mdash;N (where M denotes Ca, Mg, or rare earth element), wherein the content of O and N as non-metallic components is in the range of 0 eq %<N&lE;30 eq %, with O&plus;N&equals;100 eq %, the content of M, Al, and Si as metallic components is in the range of 20 eq %&lE;Al&lE;30 eq % and 70 eq %&lE;Si&lE;80 eq %, respectively, with Al&plus;Si&equals;100 eq % (if M does not exist) and the content of M, Al, and Si as metallic components is within the hatched area in the composition diagrams shown in FIGS.,to,, if M is Ca, Mg, or rare earth metal, or within the hatched area in the composition diagrams shown in FIGS.,to,, if the content of N is in the range of 5 eq %&lE;N&lE;25 eq %. This glass is superior in specific rigidity and fabricability. It contains nitrogen in a controlled amount so that it has improved specific rigidity without its specific gravity increasing.

Glass with high specific rigidity for recording medium

A mixed powder containing: 5-30 wt % of SiC whiskers; 3-30 wt % of a sintering auxiliary agent composed of one kind or more of oxides of Mg, Si, Ca, Ti, Zr, Cr, Ni, Y and rare earth elements; and an Al.sub.2 O.sub.3 powder as a base material; or further containing 0.5-40 wt % of one kind or more of compounds composed of one kind or more of transient elements in the groups IVa, Va, and VIa of the periodic table and one kind or more of C, N and B, are compacted and subjected to pressureless-sintering in a nitrogen containing inert gas atmosphere at a temperature between 1500.degree. and 1900.degree. C. With this method, the SiC whiskers containing Al.sub.2 O.sub.3 based ceramic material, which is densified and has a sufficient strength and toughness, can be formed in a complex shape and a large size.
