Chlorite salts
Calcium Chlorite, CaClO2, is formed by the action of chlorine dioxide, ClO2, on calcium peroxide prepared by the action of hydrogen peroxide on milk
of lime. A solution is obtained from which calcium chlorite crystallises in vacuo over potassium hydroxide, or may be precipitated by alcohol and
ether. It explodes on percussion and decomposes completely in contact with a heated wire
Strontium Chlorite, Sr(ClO2)2, is obtained by the action of chlorous acid on strontium hydroxide, followed by rapid evaporation, first over a flame
until a skin is formed, and then in vacuo. It separates as a deliquescent salt which is decomposed above 200° C., giving a mixture of chloride and
chlorate. It may also be formed by treating the precipitated peroxide with chlorine dioxide. The product explodes on percussion
Barium Chlorite, Ba(ClO2)2, is formed by the action of chloric acid on barium hydroxide in solution. It is an unstable salt, but it can be obtained in
a fairly pure condition by rapid evaporation over a flame until a skin is formed, and then further concentration in vacuo. Slow evaporation results in
the formation of the chlorate. Barium chlorite is very soluble in water, and is decomposed into chlorate and chloride at 235° C.
Silver chlorite
Silver nitrate and potassium chlorite react to form yellow crystals of the Silver chlorite, AgClO2, an unstable substance decomposing energetically at
105° C.
Lead Chlorite, Pb(ClO2)2, is obtained by precipitating lead nitrate solution with a soluble chlorite. It crystallises in yellow scales, and explodes
when heated above 100° C. A mixture of this salt with sulphur inflames when rubbed.
Can't find anymore reactions that form another chlorite salt. If anyone can ad to this.

A mix of solid Sodium Chlorite and Hydrazine Sulfate ignites spontaneously a few minutes after being mixed.

I have experience with lead chlorite. This material indeed is explosive, without the need of any added reductor/fuel. It is quite remarkable, because
it is explosive, while it does not have a combined oxidizer/reductor in one compound (like ammonium perchlorate or nitrated organics). Lead chlorite
can be stored for a long time (I have a few hundreds of mg, several years old), but on heating it explodes.
