Chlorate explosives yield only a small amount of gaseous products since the major product of explosion is potassium chloride. The specific pressure / is therefore relatively low (the high temperatures do not compensate for the small volume of gases), hence the lead block expansion is low, but Cheddites without nitro compounds—type O No. 6 and S—give an even smaller lead block expansion 180-200 cm3. Some chlorate explosives, when detonated in the open, do not transmit detonation from cartridge to cartridge, differing in this respect from dynamites and ammonium nitrate explosives. In a confined space, however, they behave differently. Here the... 

Chlorate explosives were also used in both countries, in mines, viz. Miedziankit type in Russia (p. 278) and Cheddite type in France (p. 277).

Properties of Chlorate Explosives. In general, expls based on chlorates are very powerful and brisant, but are very sensitive to friction and impact. Coating of particles of chlorates with substances such as castor oil, rosin, paraffin, tar, aromatic nitrocompds, crude rubber, vaselin, pertoleum, plastic materials, diminish considerably the sensitiveness but not sufficiently to make these expls suitable for loading artillery shells(See CHEDDITES) The chlorate expls are more sensitive than those contg perchlorates, and expls contg Na chlorate are more sensitive than those with K chlorate. Expls contg K or Na chlorate should not be mixed with Amm salts because, in this case, double decomp takes place with the formation of Amm chlorate which can explode spontaneously. It also is advisable not to use either PA or.TNCrs in chlorate expls, because such mixts are very sensitive(Ref 7,p 383). These precautions were not always followed... 

Uses of Chlorate Explosives, Most chlorate expls have been used for industrial purposes, but during WWI WWII some were used by the French, Russians, Italians, Japanese and Germans for loading mines, torpedoes, hand grenades depth charges(but not in artillery shells). Many expls contg chlorate have been used in primers and detonators (See also under individual expls, such as CHEDDITES)...

As early as 1865 Nisser [81] recommended the use of potassium perchlorate instead of potassium chlorate. Ammonium perchlorate as a constituent of explosives was proposed by Nobel [82] in 1888, and explosives with ammonium perchlorate as a chief component were proposed by Alvisi [83] in 1895 and Carlson [84] in 1897. Explosives containing ammonium perchlorate are used in Japan in the mining industry (p. 474). Yonckites, developed by Yonck [85] (p. 447) were extensively used in the Belgian mining industry. Cheddites with ammonium perchlorate instead of potassium chlorate were manufactured in France.

CSE (Explosifs). These expls were developed after WWII at the laboratory of Commission des Substances Explosives (CSE) in France. One group of expls based on chlorates or perchlorates is described uhder CHEDDITES OR STREETITES. See compn designated 55-CSE -1948 58-CSE-1948 in Table 4, Vol 2, p C159. These are called "Explosifs du type OC ... 

Many chlorate mixtures, particularly those which contain sulfur, sulfides, and picric acid, are extremely sensitive to blows and to friction. In the Street explosives, later called Cheddites because they were manufactured at Chedde in France, the chlorate is phlegmatized by means of castor oil, a substance which appears to have remarkable powers in this respect. The French Commission des Substances Explosives in 1897 commenced its first investigation of these explosives by a study of those which are listed below, and concluded 35 that their sensitivity to shock is... 

Until the end of World War I and some years after, nitro derivatives of naphthalene were fairly widely used in mixtures with other explosives, for example with ammonium nitrate (e.g. Schneiderite) or with various other nitro compounds such as picric acid, as well as with potassium chlorate (cheddit) (Vol. III).
