An igniter composition has (i) a source of copper selected from basic copper nitrate, copper oxide, copper hydroxide, and/or copper complex of guanylurea nitrate, (ii) one or more oxidizers, (iii) a binder selected from guanidine nitrate and/or guanylurea nitrate, and (iv) an inorganic fuel comprising an elemental metal or metal hydride selected from the group consisting of: titanium, silicon, aluminum, magnesium, iron, and combinations thereof. The igniter composition may be substantially free of boron or contain minimal amounts of boron. A minimum flame temperature at combustion (Tc) of ≥about 2300K (2,027° C.). Such a mixture may be spray dried to form a powder that is compacted to form a solid igniter composition, such as a pellet or grain. The mixture that is spray dried may have a heat of explosion (HEX) of ≤about 1,000 calories per gram (cal/g). Inorganic fuel can then be added to the spray-dried powder.
