1. A gas generant composition, comprising guanidine nitrate, basic copper nitrate and ammonium perchlorate, further comprising a slag-forming agent and a lubricant, wherein the slag-forming agent is at least one zirconate, at least one silicate or a mixture of
at least one zirconate and at least one silicate,
wherein contents, in percent by mass, of respective components are as follows:
guanidine nitrate 40% to 60%;
basic copper nitrate 25% to 50%;
ammonium perchlorate 0% to 7%;
slag-forming agent 1% to 10%;
lubricant 0.05% to 5%; and wherein the slag-forming agent is a mixture of strontium zirconate and barium zirconate in a mass ratio of 1:0.5-3.
