Sodium nitrate powder

MATERIALS Potassium (or sodium) nitrate, powdered sulfur, powdered charcoal. 

Sodium nitrate powder is produced by crushing the 6rystals, it also cakes gradually but does not become as hard as potassium nitrate or chlorate.

Black Powder. Black powder is mainly used as an igniter for nitrocellulose gun propellant, and to some extent in safety blasting fuse, delay fuses, and in firecrackers. Potassium nitrate black powder (74 wt %, 15.6 wt % carbon, 10.4 wt % sulfur) is used for military appHcations. The slower-burning, less cosdy, and more hygroscopic sodium nitrate black powder (71.0 wt %, 16.5 wt % carbon, 12.5 wt % sulfur) is used industrially. The reaction products of black powder are complex (Table 12) and change with the conditions of initia tion, confinement, and density. The reported thermochemical and performance characteristics vary greatly and depend on the source of material, its physical form, and the method of determination. Typical values are Hsted in Table 13. 

Sodium Antimonate. Sodium antimonate [15593-75-6] Na SbO, another antimony synergist of commercial importance, has an antimony content of 61—63 wt % and a bulk density of 39.4—46.4 kg/m. Properties are given in Table 2. It is made by oxidizing antimony trioxide using sodium nitrate and caustic. It is a white powder and has a pH of around 9—11 when dissolved in water. 

Dining outgassing of scrap uranium-aluminium cermet reactor cores, powerful exotherms led to melting of 9 cores. It was found that the incident was initiated by reactions at 350°C between aluminium powder and sodium diuranate, which released enough heat to initiate subsequent exothermic reduction of ammonium uranyl hexafluoride, sodium nitrate, uranium oxide and vanadium trioxide by aluminium, leading to core melting.

Mixtures of the nitrate with powdered aluminium or its oxide (the latter seems unlikely) were reported to be explosive [1], and the performance characteristics of flares containing compressed mixtures of the metal and nitrate have been evaluated [2]. A violent explosion in a copper smelting works was caused mainly by reaction of aluminium with sodium nitrate [3],...

Sodium sulfonate 1 has previously been prepared from NaHS03 and vinyltrimethylsilane using sodium nitrite/sodium nitrate as the radical initiator.3 In the submitters hands this protocol resulted in salt 1 as a pale tan powder in only 15-53% yield if 50% (v/v) aqueous methanol is employed as solvent. The yield of 1 could be increased to 63% if 22% (v/v) aqueous methanol is employed. An advantage of this method is the elimination of a potentially explosive perester as radical initiator. However, lower yields of 1 and the subsequent lower yield of the sulfonyl chloride 2 (53% for the sulfonylation, 35% overall from vinyltrimethylsilane) make this procedure less desirable than the method presented. The use of tert-butyl perbenzoate as the radical initiator4 not only provides 1 in a higher yield, but the subsequent conversion to 2 also proceeds in better yield. 

Though the oxidation potentials of potassium nitrate (KN KNO3) and sodium nitrate (SN NaN03) are high, both metal nitrates generate combustion products of high Mg, Thus, the specific impulse becomes low when KN or SN is used in a rocket propellant KN and SN are used as major ingredients of explosives and in pyrotechnics. KN is a weU-known material as a major component of black powder. 

Shimizu notes that potassium nitrate is not slow when used in black powder and metal-containing compositions in which a "hot" fuel is present. Sodium nitrate is quite similar to potassium nitrate in reactivity. 

Very simply, the two chemical substances involved, sodium chromate and lead nitrate, have exchanged partners to make two new substances, sodium nitrate, which remains in the solution, and lead chromate. This settles at the bottom of the liquid as a very fine yellow powder, chrome yellow.
