Abstract
An electric primer has an intrinsically conductive pyrotechnic mixture consisting of a metal powder fuel, an alkaline oxidizer, and a sensitizing fuel. The primer mixture preferably consists of about 27% titanium metal powder, about 68% potassium chlorate, and 5% boron as the sensitizing fuel. Lead thiocyanate may also be added as a further sensitizing fuel. The primer is advantageously adapted for use in airbag inflators in an automobile passive restraint system.
